Summary: Polymer membranes usually have a wide pore-size distribution, resulting in lower selectivity in ion separation compared to membranes made of crystalline porous materials. However, ion-sieving membranes based on conjugated microporous polymers with high uniform sub-nanometer pores can achieve high ion-separating performance with a sub-1 A size precision, attributed to their uniform and narrow pore-size distribution.

Summary: Substrate accessibility is a crucial factor that affects the efficiency of photoredox catalysis. Conjugated microporous polymer nanoparticles (CMP NPs) with a high photoactive surface area have shown promise in overcoming mass transfer limitations to achieve efficient photocatalysis. However, their limited dispersibility in many solvents, particularly in water, has hindered their practical application. In this study, we report a polymer grafting strategy that enhances the solvent-specific dispersibility of versatile hairy CMP NPs, while preserving their photocatalytic activity. The enhanced dispersibility of these nanoparticles in organic solvents or aqueous solutions enables high efficiency in various photocatalytic organic transformations.

Summary: This work presents the use of a water-soluble conjugated polymer as a surface ligand for gold nanoparticles to achieve plasmonic catalysis under visible light. The metal-polymer heterojunction, rich in sulfonate functional groups, contributes to the interaction between electron-donor molecules and the plasmonic photocatalyst. The tight binding of the polymer to the gold surface eliminates the need for conventional transition-metal surface cocatalysts and enhances the reactivity.

Summary: The coherence length of Frenkel excitons (N-coh) is a critical parameter for supramolecular J-aggregates, but experimentally determining its value is challenging due to discrepancies caused by different techniques. In this study, we used a combination of experimental techniques to determine the N-coh values for J-aggregates of a cyanine dye. We found that absorption spectroscopy alone is not sufficient for accurately determining N-coh, and a more comprehensive approach involving photoluminescence lifetime, nonlinear response, Stokes shift, and electron-phonon coupling strength analysis is necessary. Our results show that the N-coh of JC-1 J-aggregates ranges from 3 to 6.

Summary: This study presents a new self-oscillator model for illuminated colloidal systems. It predicts that the surface temperature of thermoplasmonic nanoparticles and the number density of their clusters jointly oscillate at frequencies ranging from infrasonic to acoustic values. Experimental results with gold nanorods strongly support the theory. These findings expand our understanding of self-oscillation phenomena and suggest the potential of colloidal systems as hosts for light-propelled machineries.

Summary: Regioselective stepwise phenylation of 4,7-diarylbenzo[c][1,2,5]thiadiazole fluorophores was achieved by a facile one-pot, three-step synthetic strategy involving sequential borylation, hydroxydechlorination, and Suzuki-Miyaura cross-coupling reactions. Selectivity was achieved by using BCl3 to install a boronic acid group in the ortho-position of only one of the diaryl groups. The introduction of ortho-phenyl groups through Suzuki-Miyaura cross-coupling resulted in twisted structures with hindered intramolecular rotation, allowing for adjustment of the fluorophore absorption and emission properties.
