An approach for achieving deep blue thermally activated delayed fluorescence (TADF) is presented. A simple carbazole-pyrimidine compound Cbz-PYR with near-UV emission and simultaneous room-temperature phosphorescence (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 of 428 nm. When used in OLED device, tCbz-mPYRs based OLED showed electroluminescence with 8.7% external quantum efficiency (EQE) and Commission Internationale de l′Eclairage (CIE) coordinates of (0.16; 0.12). In the part of experimental materials, we found many familiar compounds, such as 4,6-Dichloropyrimidine(cas: 1193-21-1COA of Formula: C4H2Cl2N2)
4,6-Dichloropyrimidine(cas: 1193-21-1) is a member of organic chlorides. Almost all organochlorine compounds are synthesized. It is widely used as intermediates, solvents and pesticides of chemical synthetic products.COA of Formula: C4H2Cl2N2
