摘要: Disclosed herein are several organic compounds having electron-transporting and/or hole-blocking performance and their preparation method use the OLEDs comprising compound. The exhibit high ionization potential (IP), electron affinity (Ea), glass transition temperature (Tg) mobility, a kind of good material with ability. devices these as one emitting layer, layer (ETL) (HBL) show improved efficiency better color purity.
