제목 High efficiency phosphorescent OLEDs using fused carbazole derivatives as high triplet energy hole transport materials
초록 We have synthesized high triplet energy hole transport materials derived from fused carbazole core structure and investigated the device performances of blue phosphorescent organic light-emitting diodes with the hole transport materials. Carbazole, indole and diphenylamine were attached as the functional groups to manage the energy levels and hole transport properties. A high triplet energy over 2.9 eV were obtained in all fused carbazole based hole transport materials and a high quantum efficiency over 20% could be achived in green and blue phosphorescent organic light-emitting diodes.
