Phenothiazine-, Dihydroacridine-, and Acridone-Based Boron Difluoride Complexes: Synthesis and Structure-Property Relationships

Boron difluoride complexes of phenothiazine, 9,10-dihydroacridine, and acridone derivatives with a pyridyl group were synthesized. Their structures, dynamic conformational behaviors, and photophysical properties, including solid-state fluorescence, were disclosed. The effects of the oxidation state of the sulfur atom in the phenothiazine derivatives on their properties were also clarified.

Automated summary

Boron difluoride complexes of phenothiazine, 9,10-dihydroacridine, and acridone derivatives with a pyridyl group were synthesized and characterized for their structures, dynamic conformational behaviors, and photophysical properties, including solid-state fluorescence. The effects of the oxidation state of the sulfur atom in the phenothiazine derivatives on their properties were also clarified.
