Abstract

A novel bipolar donor-acceptor-donor (D-A-D) type quinoxaline derivative, 2,3-di(9H-carbazol-9-yl)quinoxaline (DCQ) was designed and synthesized. The spectroscopic, thermal, photophysical and electrochemical properties of DCQ were systematically investigated. DCQ was employed as a yellow host material for phosphorescent organic light emitting diodes (PHOLEDs) having both a good electron and hole transport properties. Importantly, DCQ as a host material exhibits excellent device performance having a triplet energy of 2.46 eV The maximum quantum efficiency of 24.6% at 3% doping concentration and power efficiency of 49.6 lm/W at 5% doping concentration in yellow phosphorescent device.
