Summary: A series of tetrahedral cages functionalized with crown ether moieties were designed and synthesized, which exhibited reversible binding of ammonium cations and could be further developed as a drug delivery system. The combination of a bisammonium linker and one of the cages resulted in the formation of a supramolecular gel with multiple-stimuli responsiveness and excellent self-healing properties. The drug-loaded gel showed significantly improved cytotoxicity compared to free drugs.

Summary: Precise control of self-assembled structures in solution by tailoring molecular architecture is of great significance for the utilization of amphiphilic block copolymers. In this study, we investigated the self-assembly behavior of A'(A''B)n miktoarm star copolymer in dilute solution by changing architectural parameters. The phase behavior and self-assembled morphologies were studied using dissipative particle dynamics, and notable differences were observed in B-selective and A-selective solvents due to the effect of molecular spontaneous curvature. The results deepen the understanding of molecular design of amphiphilic block copolymers and provide theoretical guidance for preparing required morphologies in experiments.

Summary: This work focused on the preparation and characterization of semi-interpenetrating polymer network (semi-IPN) amphoteric membranes, which demonstrated better stability and proton selectivity compared to pure SPAES membranes. The amphoteric membrane effectively hindered vanadium ion crossover through the membrane, attributed to the semi-IPN structure and Donnan exclusion.

Summary: Photosensitive polyimide (BF-CA) and a macromolecular photosensitiser (BB-CA) were successfully synthesized to form BF&BB-CA blend films, which can induce uniform alignment of liquid crystal (LC) after 15 minutes of non-polarised ultraviolet light exposure. The films exhibit higher LC alignment ability and excellent thermal stability, with a pretilt angle of 0.5 degrees suitable for In-Plane Switching mode LCD.

Summary: Two kinds of photosensitive polyimide with different backbone structures were synthesised to study the impact of the flexibility of the polyimide backbone on liquid crystal alignment under non-polarised ultraviolet light. The irradiation time required for inducing uniform liquid crystal alignment was found to be shorter for one of the polyimides, and the reason behind this was investigated in detail using UV-Vis spectra and reaction kinetics of the photosensitive group.

Summary: The characteristics and resistant mechanisms of macro-fungus endophytic bacteria to cadmium were explored in this study. It was found that under cadmium stress, the morphology of the bacteria changed to reduce the threat of cadmium. Functional groups like -OH, -COOH, and -NH2 were found to play a role in the cadmium adsorption process. Additionally, the adsorption of cadmium in the sterilized strains was higher compared to the living ones.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
