Summary: The research shows that heating affects the molecular structure in crystals, leading to red-light emission. Additionally, the anthracene moiety in the ANT-H crystal undergoes conformational transformation during heating, causing the disappearance of short-wavelength emission and slower structure relaxation speed. These findings provide new insights for the molecular design of o-carborane derivatives.

Summary: In this study, two bridged carborane-anthracene dyads with dual state emission (DSE) properties were reported. Compound 2 was obtained by reducing carboranyl Schiff base 9-anthracenylidene-1-amino-o-carborane (1) with NaBH4. The photophysical properties and mechanochromism of both compounds and their silica gel composites were investigated. This work provides a simple strategy for designing and synthesizing novel carborane-containing DSE compounds and regulating solid-state luminescence for potential applications.

Summary: In this study, we designed and synthesized four o-carborane-based aggregation-induced emission molecules, two of which exhibited multiple solid-state fluorescence emissions. Mechanical stimulation caused a bathochromic shift in the fluorescence emission of CB-Ph-P from 423 nm to 608 nm, and CB-Ph-PAn showed a transition in fluorescence emission wavelength from 393 nm to 623 nm when in the solid state. Analyses including powder X-ray diffraction, photophysical properties, thermal properties, and single-crystal structure analysis were performed to gain insight into the mechanism behind their luminescence behavior.

Summary: Random copolymers containing anthracene and carborane units were synthesized via ring-opening metathesis polymerization. They exhibited various emission behaviors and mechano-chromic properties in solution and as solids. The photodimerization and photocleavage of anthracene groups in the copolymers were investigated by UV-vis spectroscopy at 350 and 254 nm, respectively. The thermal properties of the copolymers were examined from 25 to 600 degrees C under nitrogen and in air.

Summary: o-Carborane-based emitters have made significant advancements in the past decade. While extensive research has been conducted on aryl-modified o-carboranes at the carbon atom, substitution on the boron atom has been less explored. This study introduced an anthracene unit on the B(3) position of o-carborane and compared it with the previously reported C(1)-substituted regioisomer to investigate the substitution position effect, revealing its significant impact on the intramolecular charge transfer process.

Summary: Here, we present the synthesis, structure, and single-molecule conductance of three o-carborane-based molecular wires with multiple conduction channels. Through experimental and theoretical studies, we found that o-carborane-based wires have a unique three-dimensional structure that facilitates through-space transmission paths and stable molecular junction formation compared to phenyl-centered wires. The significant difference in conductance is attributed to the combination of multiple conduction channels and quantum interference. Understanding the impact of different bridging groups and anchor group substitution patterns provides valuable insights for designing multichannel molecular wires based on o-carboranes.

Summary: The mechanism and regioselectivity of Pd-catalyzed B(4)-H arylation and B(4,5)-H diarylation for o-carborane with bidentate directing groups were investigated. It was found that the rate- and regioselectivity-determining step for the whole catalytic cycle is the reductive elimination. The introduction of a substituent group on C(2) leads to significant distortion of o-carborane, making B(3)-arylation unfavorable, while counterion exchange with carboxylate before reductive elimination can increase the positive charge of palladium and lower the activation free energy.

Summary: Based on three rationally designed pyrrole-appended o-carborane derivatives, the dependence of fluorescence properties on intermolecular interaction and steric hinderance in crystalline materials is investigated. CB-NMe crystals with weaker intermolecular interaction and looser molecular packing exhibit superior fluorescence performance and temperature sensitivity. The findings have significant implications for the design and application of crystalline materials.

Summary: A novel Co-MOF based on TPE derivative was synthesized, which exhibited reversible color changes in response to different stimuli (solvent and temperature conditions). The solvatochromism of Co-MOF was attributed to the hydrogen bonding interaction between solvent molecules and coordinated water molecules, while the thermochromism was possibly caused by the desolvation process.

Summary: Recent studies have identified significant amounts of various alkyl ether moieties in milled wood lignin (SMWL), which have not been fully characterized. This study used experimental NMR data and computer simulation to analyze the different types of alkyl ether structures in SMWL. Specific regions in the HSQC spectrum were attributed to different alkyl ether moieties, but the differences were subtle and difficult to separate from other lignin moieties. Additionally, the quantification of individual alkyl ether types was challenging, and the study discussed potential formation mechanisms of alkyl ether structures in lignin biosynthesis, aging, and ball milling of wood.
