In 2014, we discovered a skeletal rearrangement of BINAMs to provide dibenzo[a,j]phenazines (DBPHZs). By making use of DBPHZs, we have succeeded in developing multi-photofunctional organic emitters based on DBPHZ-cored twisted D–A type molecules, displaying efficient thermally activated delayed fluorescence, high-contrast conformation-dictated multi-color-changing mechanochromic luminescence, and room-temperature phosphorescence.
