Guest-Molecule-Induced Glass-Crystal Transition in Organic-Inorganic Hybrid Antimony Halides.

Inorg Chem

January 2025

College of Chemistry and Materials Science, College of Environmental and Resource Sciences, Fujian Provincial Key Laboratory of Advanced Materials Oriented Chemical Engineering, Fujian Normal University, Fuzhou 350007, China.

The glassy state of inorganic-organic hybrid metal halides combines their excellent optoelectronic properties with the outstanding processability of glass, showcasing unique application potential in solar devices, display technologies, and plastic electronics. Herein, by tailoring the organic cation from -phenylpiperazine to dimethylamine gradually, four types of zero-dimensional antimony halides are obtained with various optical and thermal properties. The guest water molecules in crystal (-phenylpiperazine)SbCl·Cl·5HO lead to the largest distortion of the Sb-halogen unit, resulting in the red emission different from the yellow emission of other compounds.

Developing active-layer systems with both high performance and mechanical robustness is a crucial step towards achieving future commercialization of flexible and stretchable organic solar cells (OSCs). Herein, we design and synthesize a series of acceptors BTA-C6, BTA-E3, BTA-E6, and BTA-E9, featuring the side chains of hexyl, and 3, 6, and 9 carbon-chain with ethyl ester end groups respectively. Benefiting from suitable phase separation and vertical phase distribution, the PM6:BTA-E3-based OSCs processed by o-xylene exhibit lower energy loss and improved charge transport characteristic and achieve a power conversion efficiency of 19.

Chemical Compositions of the Marine Red Alga Laurencia composita Collected in Japan.

Chem Biodivers

January 2025

Fukuyama University: Fukuyama Daigaku, Faculty of Life Science and Biotechnology, 1 Gakuen-cho, 1 Gakuen-cho, Fukuyama, Hiroshima 729-0292, Fukuyama, JAPAN.

Marine red alga Laurencia composita was collected from seven sampling locations in Japan, and all samples were identified based on morphological studies as well as rbcL sequencing analysis. This is the first report of the isolation of (-)-8-bromo-9-hydroxy-(E)-γ-bisabolene (1) as a natural product, and bisabolene-type and β-chamigrene-type sesquiterpenes found in L. composita collected in Japan.

Single-atom catalysts (SACs) with high metal loadings are highly desirable but still challenging for large scale synthesis. Here we report a new technique named as dry-solid-electrochemical synthesis (DSES) for a general large-scale synthesis of SACs with high metal loadings in an energy-conservation and environment-friendly way. With it, a series of pure carbon-supported metal SACs (Platinum up to 35.

This work combines halogen and chalcogen bonding. Short, polarity directed C-X⋅⋅⋅Ch (X = Br or I, Ch = Se or Te) contacts were prepared by in situ low-temperature cocrystallization of liquid mixtures of neutral pentafluorohalogenobenzenes C6F5X and dimethyl chalco-genides Me2Ch. Solid-state structures of Me2Se and Me2Te were determined 150 and 125 years after their first description.
