Intramolecular arylsulfide-coordinated diboraanthracenes: effect of B–S coordination on ground-state and excited-state behavior

Year: 2025

Type: article

Abstract: isomers predominantly, where the strength of the boron-sulfur bonds can be tuned by structural and electronic modifications of the aryl groups. In the ground state, the B-S bond is cleaved upon heating in solution. In the excited state, the B-S bond undergoes dissociation, resulting in emission from tricoordinate species. The aryl groups on the sulfur atom also play a role in forming an intramolecular charge-transfer state, whereby the emissions are bathochromically shifted with large apparent Stokes shifts. Moreover, the B-S bonds are sensitive to solvent polarity and temperature, resulting in multiple emission properties depending on the surrounding environment.
