Summary: Enzymes are essential for biological transformations and have attracted great attention for their structures and functions. Biomimetic chemistry has rapidly developed in response to the demand for bioactive molecules and efficient synthesis. Biomimetic asymmetric catalysis, inspired by enzymes, has been recognized as one of the most promising strategies for producing valuable chiral compounds. This review summarizes the evolution of biomimetic asymmetric catalysis in terms of biomimetic design, catalyst development, and catalytic transformations, providing insights into bridging the gap between bio-catalysis and chemical synthesis.

Summary: We investigate the role of water in benzene methylation over ZSM-5 zeolite using solid-state NMR experiments and theoretical simulations. We find that water competes with benzene for the active sites of the zeolite and facilitates the reaction mechanism. The growth of water clusters induces a micro-hydrophobic effect in zeolite pores, which reorients benzene molecules and promotes their interactions with surface methoxy species on the zeolite.

Summary: By selectively irradiating Methylene Blue, a low-cost photocatalyst, four aromatic substrates were optimized to produce their corresponding endoperoxides in organic solvent. By combining hydrophobic substrates with a hydrophilic cyclodextrin (CyD) polymer, their photooxygenation in homogeneous aqueous environment was achieved. These results have potential applications in green homogeneous photocatalysis and delivery of oxygen releasing agents to tissues.

Summary: A tunable multipurpose separation technology was developed using a crosslinked membrane of dialdehyde-beta-cyclodextrin (DA-beta-CD) and polyethyleneimine (PEI). The coated membrane exhibited high hydrophilicity and underwater superoleophobic properties, achieving an oil/water emulsion separation efficiency of 99.9%. By adjusting the surface composition of the coated membrane, it showed excellent heavy metal ion and dye removal capabilities or superb phenol and bilirubin removal capabilities. The stable coating layer formed through the cross-linking reaction between DA-beta-CD and PEI contributed to the potential application of this technology in wastewater treatment.

Summary: A non-covalent association complex formed between a beta-cyclodextrin host and a designer bimane ditriazole guest was used to detect iodine with high sensitivity. The sub-nanomolar detection limit of this system was determined in the solution-state, and adsorbing the complex onto filter paper showed noticeable advantages over cyclodextrin-free bimane for on-paper colorimetric iodine detection.

Summary: An ultrasensitive fluorescent water sensor based on a dipodal bimane-Cu(Ⅱ) complex is developed. This sensor shows no fluorescence in the absence of water but exhibits remarkable turn-on fluorescence in the presence of extremely low concentrations of water (0.000786% v/v) through highly selective water-induced displacement of copper and restoration of the innate bimane fluorescence.

Summary: A rapid, sensitive, and practical method for detecting sulfur dioxide in aqueous solutions has been reported. The method allows for color changes to be observed with the naked eye and quantified through simple color analysis. Extensive optimization of each component revealed the unique stabilizing effect of cyclodextrin in preventing permanganate-induced degradation of the filter paper, and mechanistic analysis confirmed an oxidation-reduction reaction as the cause of the color changes observed.

Summary: This study reports the design, synthesis, and application of a highly solvatochromic coumarin derivative (compound 1) for water detection. The solvatochromism of compound 1 is attributed to the presence of an electron-withdrawing aldehyde substituent and an electron-donating diethylamino group. Compound 1 shows significant fluorescence responsiveness to polar protic solvents, especially with a pronounced decrease in fluorescence upon the addition of small amounts of water. This water-based responsiveness is utilized in the development of a fluorescent water sensor with rapid, sensitive, and irreversible fluorescence quenching to both liquid water and water vapor.
