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