An organic compound having carbazole, dibenzofuran, thiophene, and diphenylphosphine oxide, (5-(8-(9H-carbazole-9-yl)dibenzo[b,d]furan-2-yl)thiophene-2-yl)diphenylphosphine oxide(CFTPO) was synthesized and employed as a yellow host material to harvest triplet excitons from yellow triplet emitters. The CFTPO material is a bipolar host material because it includes carbazole and diphenylphosphine oxide charge transport units with both a high triplet energy 2.47eV and a high quantum efficiency of 24.7% in yellow phosphorescent device. |
