Organic photovoltaic materials have been widely used in organic solar cells (OSCs) and organic photodetectors (OPDs) systems, owing to their numerous advantages such as low cost, light weight, high structural tunability, and ease of solution processing. Among these materials, near-infrared (NIR)-responsive materials, especially those with NIR II-region (1000–1700 nm) response, are crucial in the construction of tandem OSCs and semitransparent OSCs to achieve high power conversion efficiency and high light utilization efficiency, respectively. Meanwhile, OPDs with NIR II-region response show great application potential in industrial, military, and medical fields. In recent years, some progress has been made in the development of organic photovoltaic materials and devices with NIR II-region response. This review provides an overview of the design strategies for NIR organic photovoltaic materials, followed by a classification and summary of representative organic NIR II-region responsive materials and their performance in OSCs and OPDs. Lastly, we conclude with an outlook on the development of organic photovoltaic materials with NIR II-region response.

Liquid crystal (LC) phases have been used in various self-assembly technologies owing to their stimuli-responsive characteristics. Especially, orientation-controlled LC structures on and in surfaces are extensively studied in physics, chemistry, and materials science because they can be used in patterning applications beyond the conventional LC display. The key idea in recent development is to control the surface anchoring condition between the substrate and LC materials. Specifically, defects in the LC phases have been introduced as an effective lithographic tool for fabricating distinguished patterns. In this review, the bulk and surface-induced structures of LC materials are overviewed to show the relationship between the surface characteristics of the substrates and the elastic properties of LC materials. The two main themes are (1) orientation control, which can be achieved by micro- and nano-confinement using solid and fluid substrates, and (2) the application of LC materials as optoelectronics and sensors. Finally, the review discusses the defect structures of LC materials fabricated on flexible substrates and their possible applications.

We developed a cost-effective silica gel-supported palladium nanocatalyst in a three-step reactions process. Initially, silica gel (60–120 mesh) underwent amino group functionalization using 3-aminopropyltriethoxysilane, leading to the formation of a Schiff base through a reaction with the 1,10-phenanthroline-2,9-dicarboxaldehyde ligand. Subsequently, palladium nanocatalyst was introduced to the silica matrix ligand in the presence of palladium salt and hydrazine hydrate, resulting in the formation of the silica gel-supported Schiff-base palladium nanocatalyst (Si@SBPdNPs 3). Successful functionalization of the silica matrix was confirmed using various spectroscopic techniques. FT-IR spectra demonstrated the incorporation of organic moieties onto the silica surface, while SEM images revealed the modified spherical shape of the silica gel. TEM and XRD analyses confirmed the presence of palladium on the silica matrix. ICP and EDX measurements validated the anchoring of 0.55 mmol/g of palladium to the catalyst. Additionally, XPS analysis showed the complexation of Pd(0) with the organic ligand on the silica matrix, confirming the successful integration of palladium into the system. This nanocatalyst demonstrated outstanding performance in Mizoroki-Heck reactions, yielding high product outputs in the cross-coupling of various aryl halides and olefins under mild conditions. Additionally, the nanocatalyst was effectively utilized in synthesizing Ozagrel, a thromboxane A2 synthesis inhibitor used for treating noncardioembolic stroke patients. Remarkably, the catalyst demonstrated excellent reusability, maintaining high productivity across five consecutive cycles, underscoring its economic and sustainable potential for industrial applications.

我们通过三步反应过程开发出了一种具有成本效益的硅胶支撑钯纳米催化剂。首先,硅胶(60-120 目)使用 3-aminopropyltriethoxysilane 进行氨基官能化,通过与 1,10-菲罗啉-2,9-二甲醛配体反应形成希夫碱。随后,在钯盐和水合肼的存在下,将纳米钯催化剂引入硅胶基质配体,形成了硅胶支撑的希夫碱纳米钯催化剂()。使用各种光谱技术确认了硅胶基质的成功功能化。傅立叶变换红外光谱显示了有机分子在二氧化硅表面的结合,而扫描电镜图像则显示了硅胶的改性球形。TEM 和 XRD 分析证实了二氧化硅基体上钯的存在。ICP 和 EDX 测量证实催化剂上锚定了 0.55 mmol/g 的钯。此外,XPS 分析表明钯与二氧化硅基体上的有机配体发生了络合反应,证实钯成功地融入了该体系。这种纳米催化剂在 Mizoroki-Heck 反应中表现出卓越的性能,在温和条件下,各种芳基卤化物和烯烃的交叉偶联反应中产生了大量产物。此外,该纳米催化剂还被有效地用于合成 Ozagrel(一种血栓素 A2 合成抑制剂,用于治疗非心肌栓塞性中风患者)。值得注意的是,该催化剂具有极佳的可重复使用性,可在连续五个循环中保持高生产率,这凸显了其在工业应用中的经济性和可持续发展潜力。

Liquid crystal elastomers (LCEs) are a kind of soft actuating materials with large reversible deformation ability, which can work as the “motor” to exhibit complex deformations and drive the locomotion of soft robots. The deformation of LCEs depends on the three-dimensional (3D) shape of whole structure and alignment patterns of mesogens. Various methods have been employed to fabricate the LCE structure with desired shapes and mesogen alignments. However, conventional 3D printed LCEs require continuous thermal energy input to maintain their actuated shapes. The LCEs cannot be reprocessed and reprogrammed once cured. Herein, we introduce dynamic boronic ester bonds into the ink, with which the printed LCE structures are capable of being reprogrammed from polydomain into monodomain state and vice versa. We further explore the effects of printing parameters and content of dynamic covalent bonds on the actuation performance and reprogramming ability. The actuated shape could be well predicted with finite element method. The dynamic printable LCEs developed here offer new strategy and large design space for LCE structures.

液晶弹性体(LCE)是一种具有较大可逆形变能力的软执行材料,可作为 "马达 "产生复杂形变,驱动软机器人运动。LCE 的变形取决于整体结构的三维(3D)形状和介质的排列模式。人们采用了各种方法来制造具有所需形状和中原排列的 LCE 结构。然而,传统的三维打印 LCE 需要持续输入热能以保持其驱动形状。LCE 固化后无法进行再加工和再编程。在此,我们在油墨中引入了动态硼酸酯键,这样打印出的 LCE 结构就能从多域状态重新编程为单域状态,反之亦然。我们进一步探讨了印刷参数和动态共价键含量对致动性能和重编程能力的影响。用有限元方法可以很好地预测驱动形状。本文开发的动态可印刷 LCE 为 LCE 结构提供了新的策略和广阔的设计空间。

Single crystal growth and characterization of the lithium bis(trifluoromethyl sulfonyl)imide (LiTFSI), the most common electrolyte salt for lithium-ion batteries, have been performed and succeeded in unraveling the atomic structures of its different crystalline phases. The structures of two crystalline phases (phase I: orthorhombic, Pccn; phase II: monoclinic, P21/c) have been determined through temperature-dependent X-ray crystallography of the LiTFSI single crystal on heating, and the solid-solid phase transformation between phase I and phase II has been dictated. Interestingly, a conformational change of TFSI⁻ from transoid to cisoid has been discovered during the transition from phase I to phase II, which has been further confirmed by the temperature-dependent Raman spectroscopy. The coordination of Li⁺ with the TFSI⁻ ions of different conformations has been also elucidated in the polymorphic crystalline structures. The solid-solid phase transformation of the first-order leads to the cracking of the LiTFSI crystal, probably along the lithium-ion or the fluorine-rich layer in phase II. In the molten state, the coexistence of the transoid conformation and the cisoid conformation is found in the TFSI⁻ ions, affirming the recent observation in the concentrated non-crystalline state. This work is anticipated to shed light on the (de)solvation and the transport of lithium ions in complex fluids encompassing LiTFSI electrolyte solutions from the structural aspects.

对锂离子电池最常见的电解质盐--双(三氟甲基磺酰基)亚胺锂(LiTFSI)进行了单晶生长和表征,并成功揭示了其不同晶相的原子结构。通过对 LiTFSI 单晶加热时的温度依赖性 X 射线晶体学分析,确定了两种结晶相(I 相:正交相;II 相:单斜相)的结构,并确定了 I 相和 II 相之间的固-固相转变。有趣的是,在从 I 相到 II 相的转变过程中,发现了 TFSI- 从 到 的构象变化,温度依赖性拉曼光谱进一步证实了这一点。在多晶体结构中,还阐明了不同构象的 Li⁺ 与 TFSI- 离子的配位关系。一阶固-固相变导致锂-TFSI 晶体开裂,可能是沿着锂离子层或第二阶段的富氟层开裂。在熔融状态下,TFSI- 离子中发现了构象与构象共存的现象,这肯定了最近在浓缩非晶态下的观察结果。这项工作有望从结构方面揭示锂离子在包括 LiTFSI 电解质溶液在内的复杂流体中的(去)溶解和传输。

The structure of mRNA lipid nanoparticles (LNPs) is still under debate, with different studies presenting varying morphological characteristics, significantly hindering their biomedical potential. A typical formulation process of mRNA LNPs involves three steps: initial rapid mixing of lipids in an ethanol phase and mRNA in an acidic aqueous phase, followed by the swift removal of ethanol, and finally adjusting the solution to a neutral environment. In this study, we utilize Small Angle Neutron Scattering (SANS) with contrast matching to reveal the kinetic pathway-dependent of mRNA LNPs morphology. We find that the formulation process of the Moderna COVID-19 vaccine is controlled by a competition between aggregation and microphase separation, dictating the diverse morphologies observed in mRNA LNPs. The first step leads to the formation of polydisperse spherical droplets with an average diameter of 42±6.0 nm in an acidic ethanol aqueous solution. Ethanol removal initiates both aggregation and internal microphase separation, resulting in a polydisperse core-shell structure with an average diameter of 48±3.7 nm. Heptadecan-9-yl 8-((2-hydroxyethyl) (6-oxo-6-(undecyloxy) hexyl) amino) octanoate (SM-102) binds to mRNA via electrostatic interaction to form a reverse-wormlike micelle structure inside. The 1,2-Distearoyl-sn‑glycero-3-phosphocholine (DSPC) and PEG-lipid are just in the shell and cholesterol acting as a filler throughout the core-shell structure. Upon transitioning to a neutral environment, SM-102 loses its charge and neither the periphery nor the reverse-wormlike micelle can maintain their stabilities, leading to further aggregation and microphase separation. The average diameter of core-shell structure turns to be 66±5.2 nm. In the actual formulation process of the Moderna COVID-19 vaccine, steps 2 and 3 occur simultaneously, and the competition between aggregation and microphase separation determines the final morphology. These findings offer crucial insights into optimizing the morphology of mRNA LNPs, thereby facilitating advancements in vaccine development and mRNA vaccine delivery technologies.

关于 mRNA 脂质纳米粒子(LNPs)的结构仍存在争议,不同的研究呈现出不同的形态特征,极大地阻碍了其生物医学潜力的发挥。mRNA LNPs 的典型配制过程包括三个步骤:首先将乙醇相中的脂质与酸性水相中的 mRNA 快速混合,然后迅速去除乙醇,最后将溶液调整至中性环境。在本研究中,我们利用小角中子散射(SANS)与对比度匹配揭示了 mRNA LNPs 形态的动力学路径依赖性。我们发现,Moderna COVID-19 疫苗的配制过程受控于聚集和微相分离之间的竞争,这决定了在 mRNA LNPs 中观察到的不同形态。第一步是在酸性乙醇水溶液中形成平均直径为 42±6.0 nm 的多分散球形液滴。移除乙醇后,会产生聚集和内部微相分离,从而形成平均直径为 48±3.7 nm 的多分散核壳结构。Heptadecan-9-yl 8-((2-hydroxyethyl) (6-oxo-6-(undecyloxy) hexyl) amino) octanoate(SM-102)通过静电作用与 mRNA 结合,在内部形成反向蠕虫状胶束结构。1,2-二硬脂酰-sn-甘油-3-磷酸胆碱(DSPC)和 PEG-脂质只是在外壳中,胆固醇在整个核壳结构中充当填充物。在过渡到中性环境时,SM-102 会失去电荷,外围和反向蠕虫状胶束都无法保持稳定,导致进一步聚集和微相分离。核壳结构的平均直径为 66±5.2 nm。在 Moderna COVID-19 疫苗的实际配制过程中,第 2 步和第 3 步同时进行,聚集和微相分离之间的竞争决定了最终的形态。这些发现为优化 mRNA LNPs 的形态提供了重要启示,从而促进了疫苗开发和 mRNA 疫苗递送技术的进步。

The 1,2-Distearoyl-sn‑glycero-3-phosphocholine (DSPC) and PEG-lipid are just in the shell and cholesterol acting as a filler throughout the core-shell structure. Upon transitioning to a neutral environment, SM-102 loses its charge and neither the periphery nor the reverse-wormlike micelle can maintain their stabilities, leading to further aggregation and microphase separation. The average diameter of core-shell structure turns to be 66±5.2 nm. In the actual formulation process of the Moderna COVID-19 vaccine, steps 2 and 3 occur simultaneously, and the competition between aggregation and microphase separation determines the final morphology. These findings offer crucial insights into optimizing the morphology of mRNA LNPs, thereby facilitating advancements in vaccine development and mRNA vaccine delivery technologies.</p></div>","PeriodicalId":34151,"journal":{"name":"GIANT","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666542524000936/pdfft?md5=b5ca034c995aa3c4bba5fc5ed5362f64&pid=1-s2.0-S2666542524000936-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141852624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work reports the effect of 1–5 wt% epoxidized soybean oil (ESO) addition on the thermal, mechanical, and morphological properties of polybutylene succinate (PBS). ESO acts as a chain extender as well as a mild plasticizer of PBS. N-methylimidazole (NMI) is used as a catalyst to promote the reaction between PBS and ESO, and thermal, rheological, and spectroscopic analyses demonstrate increased viscoelastic properties, compatibility, crystallinity and thermal stability of the melt reacted formulations. In the presence of NMI, storage modulus (G’) values two orders of magnitude higher than that of pure PBS are achieved, confirming the completion of the chain extension reaction. A drastic refinement of the biphasic structure of the blend is observed, with the formation of a homogenous structure where ESO is well incorporated into the matrix. Finally, tensile tests reveal enhanced mechanical performance in the blends reacted in the presence of NMI. These findings pave the way for the development of a versatile family of materials which could find potential application in sustainable biodegradable packaging.

本研究报告介绍了添加 1-5 wt%环氧化大豆油(ESO)对聚丁二酸丁二醇酯(PBS)的热、机械和形态特性的影响。ESO 既是 PBS 的扩链剂,也是一种温和的增塑剂。N 甲基咪唑(NMI)被用作催化剂来促进 PBS 和 ESO 之间的反应,热学、流变学和光谱分析表明,熔融反应配方的粘弹性能、相容性、结晶度和热稳定性都有所提高。在 NMI 的存在下,存储模量(G')值比纯 PBS 高出两个数量级,这证明链延伸反应已经完成。共混物的双相结构得到了显著改善,形成了一种均匀的结构,其中 ESO 与基质结合得很好。最后,拉伸测试表明,在 NMI 存在的情况下反应的共混物具有更高的机械性能。这些发现为开发多功能材料系列铺平了道路,这些材料可能会应用于可持续生物降解包装。

Liquid crystals, as typical anisotropic building blocks, tend to self-assemble into various ordered architectures during distinct thermodynamic processes. Research on the underlying mechanisms and rules may drastically promote our understanding of complicated structures. Here, zigzag focal conic domains (ZFCDs) are generated in rapid cooling process under an antagonistic boundary condition. After several thermal cycles beneath the nematic-smectic (N-S) phase transition point, the ZFCDs are well regularized. We found that the dislocations associated with the rapid cooling play vital roles in the formation of ZFCDs. A strong interphase correlation between the zigzag ± 1/2 disclination pairs and ZFCDs is observed above the N-S phase transition point. The orientational order inheritance and topological invariance across the phase transition indicate that similar disclination pairs exist in ZFCDs. These disclination pairs facilitate the opposite tilt direction and a half-pitch lateral shift between neighboring focal conic domains (FCDs), thus forming ZFCDs. During thermal cycles, the thermal motion of molecules induces the regularization and elimination of defect cores, further resulting in the ordered ZFCDs. Via properly controlling the cooling rate, large-area ordered ZFCDs are achieved in a wide film thickness range after thermal cycles. This study enriches the knowledge on the topological defect guided architecture of liquid crystals and may pave the way for the generation and regularization of ordered self-assembled systems.

液晶作为典型的各向异性构件,往往会在不同的热力学过程中自组装成各种有序结构。对其基本机制和规则的研究可能会极大地促进我们对复杂结构的理解。在这里,"之 "字形焦点圆锥域(ZFCD)是在拮抗边界条件下的快速冷却过程中产生的。在向列-共晶(N-S)相变点下经过数次热循环后,ZFCD 得到了很好的规整。我们发现,与快速冷却相关的位错在 ZFCD 的形成过程中起着至关重要的作用。在N-S相变点上方,我们观察到人字形±1/2位错对和ZFCD之间存在很强的相间相关性。整个相变过程中的定向顺序继承性和拓扑不变性表明,ZFCDs 中也存在类似的披露对。这些分离对促进了相邻焦点圆锥畴(FCD)之间的相反倾斜方向和半间距横向移动,从而形成了 ZFCD。在热循环过程中,分子的热运动促使缺陷核心规整化和消除,从而进一步形成有序的 ZFCD。通过适当控制冷却速率,在热循环后的较宽薄膜厚度范围内实现了大面积有序 ZFCD。这项研究丰富了人们对液晶拓扑缺陷导向结构的认识,并可能为有序自组装系统的生成和规整化铺平道路。

Ternary organic solar cells (OSCs) are the feasible and efficient strategy to achieve the high-performance OSCs. It is of great significance to develop a superior third component candidate for constructing efficient ternary OSCs. In this work, we intelligently designed and synthesized a dimerized small molecule donor by connecting two asymmetric small molecule donors with the vinyl group, which is named DSMD-βV. This innovative oligomeric molecule DSMD-βV not only exhibits the complementary absorption and the cascade energy level arrangement with PM6 and BTP-eC9, but also regulates the phase separation micromorphology based on PM6:BTP-eC9. Consequently, PM6:DSMD-βV:BTP-eC9 based ternary device exhibits the improved exciton dissociation, charge transport and decreased recombination, thus achieving a superior power conversion efficiency (PCE) of 18.26 %, surpassing PM6:BTP-eC9 based binary (17.63 %). This work indicates that the dimerized small molecule donor is able to become a promising third component candidate, which also opens up a unique idea for the construction of efficient ternary organic solar cells.

三元有机太阳能电池(OSCs)是实现高性能 OSCs 的可行且高效的策略。为构建高效的三元有机太阳能电池,开发一种优异的候选第三组分具有重要意义。在这项工作中,我们通过将两个不对称的小分子供体用乙烯基连接起来,智能地设计并合成了一种二聚小分子供体,并将其命名为 DSMD-βV。这种创新的低聚分子 DSMD-βV 不仅与 PM6 和 BTP-eC9 具有互补吸收和级联能级排列,还能在 PM6:BTP-eC9 的基础上调节相分离微形态。因此,基于 PM6:DSMD-βV:BTP-eC9 的三元器件在激子解离、电荷传输和减少重组方面均有改善,从而实现了 18.26% 的优异功率转换效率(PCE),超过了基于 PM6:BTP-eC9 的二元器件(17.63%)。这项工作表明,二聚化小分子供体能够成为一种前景广阔的候选第三组分,这也为构建高效的三元有机太阳能电池开辟了一种独特的思路。
