Summary: Three thermochromic materials (DC8, DC12, DC16) were synthesized by linking the rigid bpeb with different lengths of alkyl chains, showing remarkable fluorescent color changes under 365 nm light irradiation with temperature elevation, along with photochromic character in DC16. Differential scanning calorimetry measured phase transition temperatures higher than fluorescence color change temperatures, attributing the allochroic effect to the synergistic action of heating and photo-inducement. Reversibility of thermochromic behavior and fluorescence recovery were demonstrated by ethanol treatment.

Summary: We have reported a novel rhodium-catalyzed rearrangement reaction involving N-substituted 2-thiopyridones and diazoesters. This reaction proceeds through the rhodium-catalyzed formation of sulfur ylides, followed by a direct C-N bond cleavage, achieving N-to-C 1,4-pyridyl migration. The protocol can be used to synthesize various thiopyridines with tetrasubstituted carbon stereocenters in moderate to excellent yields, expanding the transformation pattern of sulfur ylide intermediates in rearrangement reactions.

Summary: The growing interest in metal-organic frameworks (MOFs) in the last twenty years is due to their crystallinity, structural versatility, and controlled porosity. This study synthesized three new MOFs using the TIBM organic linker, with TIBM-Cu MOF showing excellent CO2 adsorption capacity and selectivity compared to TIBM-Cr and TIBM-Al, attributed to its open Cu site and high porosity.

Summary: The study suggests that a novel metabolite MxMxBD may increase the risk of bladder carcinogenesis by exhibiting stronger mutagenicity and genotoxicity compared to o-Ans. Additionally, heterodimerizations were observed when o-Ans was coincubated with o-Tol or aniline, highlighting the importance of considering both homodimerizations and heterodimerizations in evaluating the combined exposure risk of bladder carcinogenesis.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
