| Outline of Final Research Achievements |
The goal of this research project is to develop innovative photo-functional molecular systems by controlling the meso-structures and electronic states. We systematically investigated the fundamental photophysical processes including reverse intersystem crossing and excited energy transfer using the concentration-quenching-free TADF technology, and demonstrated new photo-functions such as stimuli-responsive TADF. These achievements will contribute to the further developments of high-efficiency organic light-emitting diodes based on TADF.
