Synthesis of pyridine N-oxide-BF₂CF₃ complexes and their fluorescence properties

Pyridine N-oxide-BF₂CF₃ and-BF₂C ₂F₅ complexes and their derivatives were synthesized. Most of the complexes show fluorescence both in solution and in the solid state. By expanding the π-conjugated skeleton, the color of the fluorescence could be changed dramatically. A fluorophore with a high solvent dependency could also be produced. Since such compounds can be synthesized on a gram scale in high yield, and are stable to oxygen, water, and heat, the complexes hold great potential as organic functional materials. Too complex for simple answers: Complexes of pyridine N-oxide with BF₂CF₃ and BF ₂C₂F₅, and their derivatives were synthesized. Most of the complexes fluoresce, both in solution and in the solid state. By expanding the π-conjugated skeleton, the color of the fluorescence could be changed dramatically. Owing to their properties such complexes hold potential as organic functional materials.
