| Research Abstract |
The compounds that can undergo excited state proton transfer were studied in order for development of the novel organic solid-state luminescent materials, and following results and novel photofunctional materials are obtained.(1) Suppressing the radiationless decay process by fixation of the conformation is the effective design concept for strongly luminescent solid materials.(2) A series of compounds showing a wide variety of luminescence color are newly synthesized by tuning electronic effect of the substituent(s).(3) Luminescence switches by alteration of molecular packing with external stimuli are developed.(4) Colorless white emitting materials are obtained.
