Nowadays, reaching of industrial wastes containing durable organic pollutants to water resources is one of the important environmental problems. Cost-effective, nontoxic, thermally and chemically stable, light-sensitive photocatalysts are being developed for the removal of these wastes from water resources. Our aim in this study is to synthesize newly bis-[(4-pyrenebutoxy)]phthalocyaninato silicon (Pyrn-C₄-SiPc) and bis-[n-(9-anthrylmethyl)-n-methylamino]phthalocyaninato silicon (Anthr-C₃-SiPc) molecules and then modify onto TiO₂ nanoparticles. The sol-gel method was used during the modification process to achieve synthesis at lower temperatures to obtain nano TiO₂ crystals in the anatase form. 10% and 25% concentrations of silicon phthalocyanine-modified TiO₂ nanoparticles which are approximately around 5 nm the particle sizes were added to the preparated hybride organic-inorganic polymer network, and were applied to the glass surface by spray method. The resulting coatings’ thicknesses, photocatalytic activities, and optical, physical, morphological, and mechanical properties were tested. The adhesion of the coatings sprayed onto the glass surface was measured as 5B The coatings created were found to have high hardness and resistance in the tests conducted. This research successfully developed photocatalytic hybrid nanocomposite films that are highly transparent with 90% light transmittance exhibit robust photocatalytic activity, and remain color-stable.

如今，含有持久性有机污染物的工业废物进入水资源是重要的环境问题之一。目前正在开发具有成本效益、无毒、热稳定性和化学稳定性的光敏光催化剂，用于清除水资源中的这些废物。本研究旨在合成新的双[(4-芘丁氧基)]酞菁硅（Pyrn-C4-SiPc）和双[n-(9-蒽丙基甲基)-n-甲基氨基]酞菁硅（Anthr-C3-SiPc）分子，然后将其修饰到二氧化钛纳米粒子上。在改性过程中采用了溶胶-凝胶法，以实现在较低温度下合成，从而获得锐钛矿型纳米二氧化钛晶体。在制备好的有机-无机混合聚合物网络中分别加入 10%和 25%浓度的硅酞菁改性 TiO2 纳米粒子（粒径约为 5 纳米），并通过喷涂方法将其涂在玻璃表面。测试了所得涂层的厚度、光催化活性以及光学、物理、形态和机械性能。喷涂到玻璃表面的涂层的附着力测量值为 5B 在进行的测试中发现，所制作的涂层具有很高的硬度和耐受性。这项研究成功开发出了光催化混合纳米复合薄膜，其透光率高达 90%，具有很强的光催化活性，并且颜色稳定。

The zirconium/niacin metal-organic framework (MOF) was prepared by an efficient solvothermal method and the nanostructure of MOF was identified by IR, SEM, EDX, XRD, BET and TEM. The prepared Zr-MOF was evaluated as a catalyst in organic synthesis. Tetrahydro xanthene-1,8‑dione derivatives were synthesized by a one-pot reaction between 2 mol of dimedone and 1 mole of aromatic aldehyde in the presence of the catalytic amount of Zr-MOF under solvent-free conditions. The prepared ligands were evaluated as COX-1 and COX-2 inhibitors and the data obtained explained that the ligands 4-(3,3,6,6-tetramethyl-1,8-dioxo-2,3,4,5,6,7,8,9-octahydro-1H-xanthen-9-yl)phenyl benzoate (3 g), 3,3,6,6-tetramethyl-9-(5-methylfuran-2-yl)-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)‑dione (3i) and 9-(3-(4-chlorophenyl)-1-phenyl-1H-pyrazol-4-yl)-3,3,6,6-tetramethyl-3,4,5,6,7,9-hexahydro-1H-xanthene-1,8(2H)‑dione (3j) gave the promised data.

Ferrocene-based burning rate catalysts (BRCs) are essential for controlling the combustion of ammonium perchlorate (AP)-based composite solid propellants. However, their efficacy is often limited by migration during storage, leading to performance degradation. This work reports a novel class of covalently grafted ferrocene-functionalized multi-walled carbon nanotubes (CNT-Fc-n, n = 1, 2, 3) exhibiting enhanced catalytic activity and anti-migration properties. Structural characterization confirmed successful functionalization, while electrochemical analysis revealed facilitated electron transfer during AP decomposition due to π-π conjugation within the CNT-Fc-n structure. Consequently, CNT-Fc-n catalysts significantly reduced the AP decomposition activation energy, with CNT-Fc-3 (highest ferrocene loading) demonstrating the most pronounced catalytic effect. Specifically, CNT-Fc-3 lowered the AP decomposition temperature by 103 °C and 39 °C compared to pure AP and Catocene-catalyzed AP, respectively. Kinetic analysis revealed a 28-fold increase in the rate constant for CNT-Fc-3 catalyzed AP decomposition compared to pure AP. Moreover, the unique architecture of CNT-Fc-3 significantly reduced migration during a 50 °C simulation. This work presents a promising strategy for developing high-performance, migration-resistant BRCs for next-generation solid propellants.

二茂铁基燃烧速率催化剂（BRC）对于控制高氯酸铵（AP）基复合固体推进剂的燃烧至关重要。然而，它们的功效往往受到储存过程中迁移的限制，从而导致性能下降。本研究报告了一类新型共价接枝二茂铁功能化多壁碳纳米管（CNT-Fc-n，n = 1、2、3），它们具有更强的催化活性和抗迁移特性。结构表征证实了功能化的成功，而电化学分析表明，CNT-Fc-n 结构中的π-π共轭作用促进了 AP 分解过程中的电子转移。因此，CNT-Fc-n 催化剂显著降低了 AP 分解活化能，其中 CNT-Fc-3（二茂铁负载量最高）的催化作用最为明显。具体而言，与纯 AP 和二茂铁催化的 AP 相比，CNT-Fc-3 将 AP 分解温度分别降低了 103 ℃ 和 39 ℃。动力学分析表明，与纯 AP 相比，CNT-Fc-3 催化 AP 分解的速率常数增加了 28 倍。此外，CNT-Fc-3 的独特结构大大减少了 50 °C 模拟期间的迁移。这项工作为开发用于下一代固体推进剂的高性能、抗迁移 BRC 提供了一种前景广阔的策略。

Using Density functional theory (DFT), we investigated the charge storage capacity, quantum capacitance (C_Q), geometry and electronic structures of BNyne/graphene heterostructures (BNyneGHs), as well as the impact of transition-metal dopants on their C_Q. Our results showed that doping was more effective than vacancy defects in improving the C_Q of BNyneGHs. Ti-doped BNyneGHs exhibited the highest C_Q value of 360.08 μF/cm², making them ideal positive electrode materials for supercapacitors (SCs). The presence of doping agents was found to enhance the density of states (DOS) around the Fermi level, resulting in improved C_Q. Our calculations identified potential cathode or anode materials for high-energy-density SCs, providing theoretical support for the design of high-capacitance SCs.

我们利用密度泛函理论（DFT）研究了硼炔/石墨烯异质结构（BNyne/GHs）的电荷存储容量、量子电容（CQ）、几何形状和电子结构，以及过渡金属掺杂物对其 CQ 的影响。我们的研究结果表明，在改善 BNyneGHs 的 CQ 方面，掺杂比空位缺陷更有效。掺杂钛的 BNyneGHs 的 CQ 值最高，达到 360.08 μF/cm2，是超级电容器 (SC) 理想的正极材料。研究发现，掺杂剂的存在提高了费米级附近的状态密度（DOS），从而改善了 CQ。我们的计算为高能量密度超级电容器确定了潜在的阴极或阳极材料，为高电容超级电容器的设计提供了理论支持。

Reactions of a series of trichlorosilanes RSiCl₃ (R = Me, tBu, Bn, Ph, Vi, Cl) and the tris(trimethylsilyl) derivative of nitrilotris(methylenephenylphosphinic) acid (NTPA(SiMe₃)₃) proceeded with transsilylation (release of Me₃SiCl) and afforded the respective silatrane-like cage compounds of the type N(CH₂P(=O)(Ph)O)₃SiR (NTPA(SiR), R = Me, tBu, Bn, Ph, Vi, Cl). According to single-crystal X-ray diffraction analyses (for R = Me, tBu, Bn, Ph, Vi) and DFT analyses (R = Me, Cl), these compounds accommodate [4+1]-coordinate Si atoms in a capped tetrahedral coordination sphere. The environment of the N atom is trigonal pyramidal, with the lone pair pointing toward the Si atom with N⋅⋅⋅Si distances in the range of 2.7451(12) Å (R = Bn) to 2.827(5) Å (R = tBu). For R = Cl, N⋅⋅⋅Si distances were calculated at the PBE0 level to be 2.748 Å in the isolated molecule, 2.620 Å in a chloroform solvate of the type NTPA(SiCl)(HCCl₃)₃. Analyses of the Intrinsic Bond Orbitals (IBOs) and Natural Localized Molecular Orbitals (NLMOs) revealed polarization of the N-located lone pair toward Si, with only marginal orbital contribution of the Si atom in the resultant NLMO (ca. 1.4% for R = hydrocarbyl, 2.2% for R = Cl, 3.3% for R = Cl(HCCl₃)₃).

一系列三氯硅烷 RSiCl3（R = Me、tBu、Bn、Ph、Vi、Cl）和氮基三(亚甲基苯基膦)酸的三(三甲基硅)衍生物（NTPA(SiMe3)3）发生了反式硅烷化反应（释放出 Me3SiCl），并得到了相应的 N(CH2P(=O)(Ph)O)3SiR（NTPA(SiR)，R = Me、tBu、Bn、Ph、Vi、Cl）型硅烷基笼状化合物。根据单晶 X 射线衍射分析（R = Me、tBu、Bn、Ph、Vi）和 DFT 分析（R = Me、Cl），这些化合物的四面体配位层中含有 [4+1] 配位的硅原子。N 原子的环境呈三叉金字塔形，孤对指向硅原子，N⋅⋅⋅Si 间距在 2.7451(12) Å（R = Bn）到 2.827(5) Å（R = tBu）之间。对于 R = Cl，在 PBE0 水平上计算出的 N⋅⋅Si 距离在孤立分子中为 2.748 Å，在 NTPA(SiCl)(HCCl3)3 型氯仿溶液中为 2.620 Å。对固有键轨道 (IBO) 和天然局域分子轨道 (NLMO) 的分析表明，位于 N 位置的孤负对向硅极化，在由此产生的 NLMO 中，硅原子的轨道贡献微不足道（R = 碳氢基时约为 1.4%，R = Cl 时约为 2.2%，R = Cl(HCCl3)3 时约为 3.3%）。

The homoleptic phosphine with the bulky perchlorophenyl group, (C₆Cl₅)₃P (1), exhibits trigonal pyramidal structure (TPY-3), yet considerably flattened: Σ(C–P–C') = 321.0(1)°. Key steric and electronic properties of this simple organophosphorus species have been estimated by calculation. Attending to its characteristic features, 1 can be rated as a deactivated phosphine, where the less-basic P atom is sterically shielded by the bulky C₆Cl₅ groups. This marked inertness notwithstanding, it has been possible to obtain (under harsh conditions) derivatives with phosphorus in high oxidation state, namely the phosphine oxide (C₆Cl₅)₃PO (2) and the difluorophosphorane (C₆Cl₅)₃PF₂ (3). These four- and five-substituted derivatives respectively exhibit trigonal pyramidal (TPY-4) and trigonal bipyramidal (TBPY-5) structures. The Σ(C–P–C') value steadily increases along the series 1–3, according to the referred structural variation. The P–C bond length is, in turn, invariably maintained at about 185 pm regardless of the different oxidation state, the increasing number of substituents around the P atom and the overall geometry. The hypervalent difluorophosphorane (C₆Cl₅)₃PF₂ (3) dissociates one of the axial fluorides in the gas phase giving rise to the fluorophosphonium cation [(C₆Cl₅)₃PF]⁺, as detected by mass spectrometry. This cation is identified as a Lewis superacid.

带有笨重全氯苯基的同性膦 (C6Cl5)3P (1) 呈三叉金字塔结构 (TPY-3)，但相当扁平：σ(c-p-c') = 321.0(1)°。我们通过计算估算了这种简单有机磷物种的主要立体和电子特性。根据其特征，1 可被定性为一种失活膦，其中碱性较低的 P 原子被体积较大的 C6Cl5 基团立体屏蔽。尽管存在这种明显的惰性，但（在苛刻的条件下）仍有可能获得磷处于高氧化态的衍生物，即氧化膦 (C6Cl5)3PO (2) 和二氟磷烷 (C6Cl5)3PF2 (3)。这些四代和五代衍生物分别呈现出三叉金字塔（TPY-4）和三叉双金字塔（TBPY-5）结构。根据所述的结构变化，Σ(C-P-C')值沿着 1-3 系列稳步上升。反过来，无论氧化态如何变化，P 原子周围取代基的数量和整体几何形状如何增加，P-C 键的长度始终保持在 185 pm 左右。高价二氟磷烷 (C6Cl5)3PF2 (3) 在气相中会解离出一个轴向氟化物，从而产生氟鏻阳离子 [(C6Cl5)3PF]+，质谱法检测到了这一阳离子。这种阳离子被认定为路易斯超酸。

A denitrogenative alkylation of N-aryl benzotriazinones using readily available α-olefins as alkyl sources via a hydroboration/palladium-catalyzed alkyl Suzuki coupling sequence is reported to afford ortho n-alkyl benzamides in good to excellent yields. Scope and limitations of the sequential hydroboration/Suzuki coupling protocol have been explored, showing large steric effects of both benzotriazinone core and alkylboranes. Only primary alkyl group of trialkylboranes from anti-Markovnikov hydroboration of α-olefins could be effectively coupled, making the protocol highly selective for ortho n-alkyl benzamides.

据报道，使用现成的 α-烯烃作为烷基来源，通过硼氢化/钯催化的烷基铃木偶联顺序，对 N-芳基苯并三嗪酮进行脱氮烷基化反应，可以得到正交 n-烷基苯甲酰胺，收率良好甚至极佳。对氢硼化/铃木偶联顺序的范围和局限性进行了探讨，结果表明苯并三嗪酮核心和烷基硼烷都有很大的立体效应。只有来自 α-olefins 的反马尔科夫尼科夫硼化反应的三烷基硼烷的伯烷基才能有效偶联，这使得该方案对正交正烷基苯甲酰胺具有高度选择性。

In mechanistic, three possible pathways of α-C(sp[2])−H functionalization amination of picolinamide with morpholine catalyzed by Cu(OAc)₂/O₂ in p-xylene were studied. Through theoretical calculations, it was found that the pathway involving the radical-cation intermediates produced by the subsequent single electron transfer (SET) was proved to be the most favorable. Then, we also discussed the solvation and substituent effects of three key steps, including N − H bond deprotonation, C − N bond formation rate-determining step and C − H bond deprotonation step, so as to fully understand the mechanism of directing group-assisted copper-catalyzed α-C − H functionalization of aniline and the screening of substrates and solvents. In thermodynamic, the SET process plays a crucial role in the entire catalytic cycle. Therefore, we further studied the reduction potential (E_red) values of Cu(II) radical-cation intermediates involved in the SET process, reflecting the occurrence trend of SET from the thermodynamic point of view, and studied the substituent effects and structure-activity relationships on E_red values of Cu(II) complexes derivatives formed by different Cu(Ⅱ) catalysts, different directing groups, different alkylamines and aromatic amines substrates. It is also found that there are many quantitative structure-activity relationships between E_red and the singly occupied molecular orbital (SOMO) energy, Hammett substituent constant σ⁺ and other structural parameters.

从机理角度研究了 Cu(OAc)2/O2 在对二甲苯中催化皮啶酰胺与吗啉的 α-C(sp[2])-H官能化胺化反应的三种可能途径。通过理论计算，我们发现随后的单电子转移（SET）产生的自由基-阳离子中间体是最有利的途径。随后，我们还讨论了 N - H 键去质子化、C - N 键形成速率决定步骤和 C - H 键去质子化步骤等三个关键步骤的溶解和取代基效应，从而全面理解了定向基团辅助铜催化苯胺 α-C - H 功能化的机理以及底物和溶剂的筛选。在热力学中，SET 过程在整个催化循环中起着至关重要的作用。因此，我们进一步研究了参与 SET 过程的 Cu（II）自由基阳离子中间体的还原电位（Ered）值，从热力学角度反映了 SET 的发生趋势，并研究了不同 Cu（Ⅱ）催化剂、不同指导基团、不同烷基胺和芳香胺底物形成的 Cu（II）配合物衍生物的取代基对 Ered 值的影响及构效关系。研究还发现，Ered 与单占分子轨道（SOMO）能、哈米特取代常数 σ+ 及其他结构参数之间存在许多定量的结构-活性关系。

A catalyst named PdNPs-DDIL@PS has been synthesized by immobilizing PdNPs on a DABCO Dicationic Ionic Liquid (DDIL) supported on Merrifield Resin (PS). The PdNPs (∼4.16 nm size) generated in situ were fully characterized using different techniques such as SEM, TEM, TGA-DTA, and XPS. It has been found that the catalyst is highly active in the Suzuki coupling reaction of various aryl bromides and aryl boronic acids in 70 % aqueous ethanol at room temperature. The catalyst produced the desired Suzuki coupling products in good to excellent yields. Additionally, the protocol was extended for the Heck coupling reactions in DMF at 80 °C with good to excellent yields. The catalyst attained a good turnover number (TON) of 160.00–189.92 and a turnover frequency (TOF) of 8.493–18.992 min⁻¹ for the Suzuki and TON of 173.33–189.77 and TOF of 3.952–6.325 min⁻¹ for the Heck coupling reactions. The catalyst displayed at least four times recyclability for the Suzuki coupling without a substantial decrease in product yields. Additionally, it boosts impressive environmentally-friendly credentials in Suzuki coupling reactions.
