Aqueous rechargeable batteries using abundant multi-ion cations have received increasing attention in the energy storage field for their high safety and low cost. Layered double hydroxides (LDHs) possess a two-dimensional structure and exhibit great potential as cathodes for multi-ion intercalation. However, the insufficient active sites of LDHs result in low capacities in the discharging process. Interestingly, the LDHs after the deprotonation process exhibit favorable electrochemical performance of multi-cation intercalation. The deprotonation process of LDHs has been widely found in the oxygen evolution reaction and energy storage field, where LDHs lose H in laminates and converts to deprotonated γ-phase MOOHs (MOOs). Herein, we take a comprehensive overview of the dynamics structure transformation of the deprotonation process of LDHs. Furthermore, the development of advanced aqueous battery cathode and metal battery anode based on deprotonated LDHs for energy storage is explored and summarized. Finally, the perspective of deprotonated LDHs in the energy storage field is discussed.

The smart emulsification and demulsification system with the light response is a useful tool in various industries, including green chemistry, catalytic reaction, pharmaceuticals, and environmental remediation. Herein, an ionic liquid crystal compound with a light triggered switch based on the azobenzene group [(4-{3-methyl-1-[3-(8-octyloxyoctyl)oxy-4-oxobutanoyl]imidazo-lium-1-yl}octyl)oxy] -N-(4-methylphenyl)benzene-1,2-diazene bromide (MOIAzo), was designed and synthesized, which could cause reversible transition between emulsification and demulsification through the light trigger. The ionic liquid has an efficient photoinduced liquefaction process, which dramatically lowers the melting point of ionic liquids from 79 to 9.2 oC. This significantly broadens the liquid state temperature of the ionic liquid crystal. The ionic liquid crystal MOIAzo exhibits both photoinduced and thermally induced nematic liquid crystal properties. The smart emulsion system was effectively employed in an eco-friendly water-saving dyeing process of cationic dyes for cationic dyeable polyester (CDP) fabrics, which used only half the amount of water compared with the conventional water bath dyeing method. After dyeing, the oil and water phases can be efficiently separated through the light irradiation, and the oil phase can be reused for the subsequent dyeing process. This novel smart emulsion dyeing method greatly reduces the water consumption and wastewater discharge. MOIAzo as a light-triggered ionic liquid molecule opens up new dimensions in green chemistry.

Smart chiral liquid crystal elastomers are a class of soft photonic crystals with periodic nanostructures. There are two kinds of chiral liquid crystal elastomers with structural colors: cholesteric liquid crystal elastomers with a one-dimensional helical nanostructure and blue-phase liquid crystal elastomers with a three-dimensional photonic crystal nanostructure. The self-assembled nanostructure of chiral liquid crystal elastomers can be dynamically controlled under external stimulation, and the reflected color can be adjusted throughout the visible light range. Along with the development of innovative material systems and cutting-edge manufacturing technologies, researchers have proposed diverse strategies to design and synthesize chiral liquid crystal elastomers and have thoroughly investigated their properties and potential applications. Here, we provide a systematic review of the progress in the design and fabrication of smart chiral liquid crystal elastomers, focusing on the cholesteric liquid crystal elastomers via surface-enforced alignment, bar coating, 3D printing, anisotropic deswelling methods as well as the three-dimensional self-assembly of blue-phase liquid crystal elastomers without additional alignment. Smart chiral liquid crystal elastomers are able to respond quickly to external stimuli and have a wide range of applications in areas such as adaptive optics, color-changing camouflage, soft robotics, and information encryption. This review concludes with a perspective on the opportunities and challenges for the future development of smart chiral liquid crystal elastomers.

Glutathione (GSH)-activated prodrugs are promising for overcoming the limitations of conventional anti-tumor drugs. However, current GSH-responsive disulfide groups exhibit unregulated reactivity, making it impossible to precisely control the drug release rate. We herein report a series of GSH-responsive prodrugs with a “three-in-one” molecular design by integrating a fluorescence report unit, stimuli-responsive unit and chemodrug into one scaffold with tunable aromatic nucleophilic substitution (SNAr) reactivity. The drug release rate of these prodrugs is tailored by modification of substituent groups with different electron-withdrawing or -donating abilities on the BODIPY core. Furthermore, the prodrugs self-assemble in water to form nanoparticles that serve as photosensitizers to produce reactive oxygen species upon irradiation for photodynamic therapy (PDT). The PDT process also increases the concentration of GSH in cells, further promoting the release of drugs for chemotherapy. This strategy provides a powerful platform for sequential photodynamic and chemotherapy with tunable drug release rates and synergistic therapeutic effects.

The multifaceted switches are part of our everyday life from the macroscopic to the molecular world. A molecular switch operating in the solution and in the crystalline state is very different. In this review, we summarize the state-of-the-art of smart molecular crystal switches based on molecular martensites. These crystal switches respond to external stimuli and reversibly change between states, retaining their macroscopic integrity. The operation of the switches predominantly relies on temperature alterations or mechanical stress, with emerging methods based on photothermal effects, photoisomerization, and host-guest chemistry. The capability of changing the molecular orientation and interaction in smart molecular crystal switches offers opportunities in several applications, including actuators, reversibly shaping structural materials, optoelectronic and magnetic materials, as well as switchable porous materials. Smart molecular crystal switches have vast potential in modern scientific and technological progress. The ongoing research shapes a rich landscape for innovation and future scientific exploration across diverse disciplines.

It is a great challenge to discover novel chemical reactions suitable for biological analysis in a living system. The development of novel protein thiol blocking agents is a crucial need for exploring protein thiol functions in protein refolding, signal transduction, and redox regulation. We are always keen on seeking novel chemical reactions applied to endogenous biological macromolecules or protein thiol sensing, blocking, and labeling. In the present work, we have successfully developed a novel agent to block protein thiol by enhanced electron-withdrawing inductive effects. This sensing and blocking process was detailedly monitored by UV-vis, fluorescent spectra, and SDS-Page gel separation. The spectral studies demonstrated that the agent could react ultrafastly with thiol within seconds at μM level. Furthermore, fluorescent imaging in cells and in vivo was further used for the validation of its ability to sensing and blocking thiol, providing evidence of downregulated protein thiols in Parkinson's disease. The enhanced electron-withdrawing inductive effect strategy in this work may provide a general guideline for designing protein thiol agent.

Metastable endoperoxides with beta-amyloid fibrils targeting benzothiazole moieties were designed and synthesized. Singlet oxygen released from these endoperoxides by thermal cycloreversion reaction was shown to cause significant structural changes on the amyloid assemblies. Most importantly, the cytotoxicity of the beta-amyloid fibrils on the PC12 cells were significantly reduced in the presence of endoperoxides. This observation, coupled with the fact that neither external oxygen, nor light is needed for this transformation, is very promising.
