The new heteroleptic iridium complexes bearing 2-(5-phenyl-1, 3, 4-oxadiazol-2-yl) phenolate (ODZ), were synthesized and characterized for application to organic light- emitting diodes (OLEDs). As main ligands (C∧ N), the anions of 2-phenylpyridine (ppy), 2- phenylquinoline (pq) and 2-(2, 4-difluorophenyl) pyridine (F2-ppy) were chelated to the iridium center and 2-(5-phenyl-1, 3, 4-oxadiazol-2-yl) phenolate (ODZ) was introduced as ...
