Summary: The present study demonstrates the synthesis of nanocomposites with a polymeric matrix and silsesquioxane-type structures, aiming to combine the advantages of hardness and strength from the inorganic phase and elasticity and toughness from the organic matrix. The incorporation of POSS improved the vitrimeric behavior of the materials by reducing relaxation times and increasing storage moduli. The modified materials showed high transparency and enhanced toughness.

Summary: In this study, we demonstrate the control of crystal size and orientation in silver phenylselenolate (AgSePh) by adding solvent vapors during chemical transformation. By testing 28 different solvent vapors, we show that the choice of solvent vapor can greatly improve the crystal size and orientational homogeneity of AgSePh. Particularly, solvents known to form complexes with silver ions result in the largest crystal dimensions and parallel crystal orientation. Moreover, AgSePh films grown with DMSO vapor exhibit improved crystalline quality and optical properties.

Summary: The emergence of hybrid organic-inorganic perovskites (HOIPs) has made significant progress in the field of photovoltaics, and the modification of organic cations has been shown to improve the performance of HOIPs. This review summarizes the influences of organic cation rotation on the structure, optoelectrical properties, and stability of HOIPs, and provides theoretical insights into the effects of organic cations in experiments. Possible control methods and development directions are also proposed to better observe and utilize the rotation of organic cations in perovskite materials, solar cells, LEDs, photocatalysis, photothermal conversion, and other related fields.

Summary: This study demonstrates a new PVK-based thermochromic composite that can reversibly switch from a transparent state to a colored state with fast kinetics. The thermochromic mechanism is based on the reversible disassembly/assembly of PVK mediated by intercalating polymeric chains, through the formation and breaking of hydrogen bonds between polymer and perovskite. Unlike other thermochromic perovskites, this system can perform multiple heating/cooling cycles regardless of environmental conditions.
