摘要： Novel organometallic compounds are provided, which include a 2-phenylpyridine iridium (Irppy) complex having alkyl and/or aryl substituted ligands and a heteroleptic or a homoleptic nature. These materials may be advantageously used in OLEDs to tune evaporation temperature and solubility, narrow emission, and increase device efficiency.
