研究実績の概要 |
The goal of this project is to design new pure-organic TADF and CPL emitters for the development of new CP-OLED. Recently, circularly polarized light has been considered for efficient growth of plants and efficient circularly polarized light sources are desired for cultivating plants at the Plants manufacturing systems. The present targets become much important for future green society with simultaneous development of society of low-energy consumption and industrial development. This research is divided in two parts: synthetic organic chemistry and photo-physical analyses. We have developed a series of promising molecules in-silico and also in-flask. A new class of BODIPY dimers with chiral and achiral units shows efficient CPL and enhancement upon aggregation to molecular wires. After this trials on the first stage, we also developed photophysical characterizations including ultra-first fluorescence decay analysis. Typical two component decay profile is essential for TADF phenomena. We also considered to develop new TADF substances which are based on semi-planar aromatic units. After development of typical D-A structures, it became sensitive to oxygen, which is typical behavior for the TADF substances.
