Abstract
A novel bipolar compound with a thiophene modified 9-phenylcarbazole and phosphine oxide moieties, (5-(4-(9H-carbazol-9-yl)phenyl)thiophen-2-yl)diphenylphosphine oxide (CPTPO), was synthesized and characterized as a high triplet energy host material. Bipolar charge transport character and a high triplet energy of 2.72 eV of CPTPO allowed the development of blue phosphorescent organic light-emitting diodes with an external quantum efficiency of 18.4%.
