Outline of Final Research Achievements

We have synthesized and characterized 2,6-diaminobenzophenone derivatives and 2-aminoisophthalic acid diesters, and demonstrated that the new luminophores in the solid state and/or in a PMMA thin film exhibited thermally activated delayed fluorescence. These results indicate that molecular design of 2,6-bis(donor)-1-acceptor-substituted benzenes and 1,6-bis(acceptor)-2-donor-substituted benzenes is valid for attaining thermally activated delayed fluorescence. We confirmed that 2,6-diaminobenzophenone derivatives could act as molecular thermometers.
