제목 Auxillary Acceptor molecules of Blue Emitting Materials for Thermally Activated Delayed Flourescent
초록 We have developed two blue thermally activated delayed fluorescence(TADF) emitters, TAZtCZ-1 and TAZtCz-2 based on an auxillary acceptor molecular design. These two emitters can control acceptor strength of triazine moiety by introducing another accepting moiety for controlled emitting wavelength. The t-butyl replaced carbazole unit was used as a donor. The two emitters showed small singlet and triplet energy gap(〖∆E〗_ST) below 0.2 eV. Maximum external quantum efficiency of two emitters showed above 20% and the color coordinate of (0.21, 0.42) and (0.15, 0.17).
