Outline of Final Research Achievements

Effects of molecular structures on photoinduced solid-state coloring behavior of tetracoordinated cationic boron complexes were revealed. Modifying the nitrogen-containing ligand, its substituents, and the counteranion provides a wide variation in the photoinduced solid color, while the structure of the substituents on the boron atom is critical to gain the photoresponsive capability. Observations of the photoproducts suggested that the photoreaction in the solid state of the complexes formed the visible-colored radical products.
