Summary: Crystallographic and computational studies suggest favourable interactions between polarizable arenes and halogen atoms. However, quantification of these interactions in solution has been hindered by the steric demands of the halogens. This study synthesized molecular balances and used H-1 NMR spectroscopy to quantify halogen-arene contacts in various solvents, revealing that the interaction trend is aligned with increasing exchange repulsion rather than dispersion.

Summary: In this study, it was found that the nanochannel spacing and membrane thickness of graphene oxide based nanofiltration membranes (GONMs) impact the cation-pi interaction, which in turn affects the desalination performance and dye removal efficiency. By regulating these parameters, the rejection rates of various salts and dyes were significantly improved, indicating the potential for a powerful GONMs-based platform for water treatment in the future.

Summary: Mpipi is a multiscale coarse-grained protein model that quantitatively describes the change in protein critical temperatures with respect to amino acid sequence, considering the dominant role of pi-pi and hybrid cation-pi/pi-pi interactions, and the stronger attractive contacts of arginines compared to lysines. Experimental benchmarks demonstrate that Mpipi predictions are in good agreement with experimental results, and the model can accurately predict protein-RNA interactions and liquid-liquid phase separation trends of proteins with sequence mutations.

Summary: The study presents a novel supramolecular polymer with a reversed viscosity/temperature profile, formed by ditopic monomers that transform from small cyclic structures at low temperatures to supramolecular polymers at elevated temperatures. The effect is shown to depend on solution concentration and solvent polarity, making the system a potential viscosity index improver in working fluids.

Summary: A series of reactive binaphthyl-diimine-based dopants are prepared and investigated for their potential in chiral induction of structural coloration in nematic liquid crystal mixtures and selective photonic sensing of NO2. The system shows high selectivity for NO2 and responds to concentrations as low as 100 ppm, with a concentration-dependent shift of the reflectance wavelength. Incorporation of copper ions improves the sensor's properties in sensitivity and selectivity, allowing customized adjustment of the system's performance.

Summary: The synthesis of arginine-derivatives using copper-catalyzed alkyne-azide click reactions has been studied. While it allows for good yields with almost no loss of stereopurity, further transformation may lead to racemization at the alpha-carbon. Caution is advised when using this highly useful modification strategy for alpha-azido amino acids.

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.
