Abstract

A new host material for use in phosphorescent OLEDs with desirable electronic properties has been synthesized. The material exhibits superior carrier-transport properties, a narrow optical band gap, relatively high triplet energy, and high thermal stability. It is synthesized by integrating hole-transporting carbazole groups into an electron-transporting phenanthroline core (see figure), and is demonstrated to be an excellent host for phosphorescent dopant emitters.

34. As BPhen has a HOMO level of 6.4 eV it does not block the holes efficiently from CBP layer (HOMO = 6.1 eV). As a result there is an initial increase in the efficiency of the Ir(ppy)3doped CBP‐based device at low current density reaching a maximum value and then a decrease with increasing current density.
