Isoelectronic Push-Pull Fluorescent Difluoroborates: Halogen Bonding and Photophysical Properties.

ABSTRACT: The structural and photophysical properties in the halogen bonding environment were thoroughly studied for a newly synthesized series of fluorescent dyes and their model derivatives. The analysis revealed that the ground-state interactions among both series are likewise. The fluorescent dyes have push-pull topology, and there is a low-lying charge-transfer (CT) excited state in their electronic structure. In order to study the effect of intermolecular interactions on the photophysical parameters of the CT excited state, a palette of solvents was used (C₆F₆, C₆F₅Cl, C₆F₅Br, and C₆F₅I). Our studies revealed that the weak halogen bonding between the perfluorohaloarene solvent and the heterocyclic core of t
