Achieving efficient deep-blue TADF in carbazole-pyrimidine compounds
activated delayed fluorescence (TADF) is presented. A simple carbazole-pyrimidine compound Cbz-PYR with near-UV emission and simultaneous room-temperaturephosphorescence (RTP) was selectively modified by lowering the singlet state energy, simultaneously preserving high triplet energy. The modified compound tCbz-mPYRs was shown to be efficient TADF emitter with 0.5 solid-state emission yield and peak wavelength
