The invention provides an azaspirocyclic compound and its application in organic photoelectric devices. The compound can be applied to organic photoelectric devices, especially organic electroluminescent devices (OLEDs), organic field effect transistors (OFETs), It can be used as a hole-transporting material, hole-injecting, and electron-blocking material in batteries, etc., and can also be used as a host material or an emitter material in OLEDs. Since the azaspiro compound has adjustable energy levels, other functional layer materials have good energy level matching, high glass transition temperature, good thermal and light stability, and the triplet energy level meets the requirements of exciton binding. The organic electroluminescent device (OLED) has the advantages of high efficiency, low operating voltage and long service life, and has good application prospects. |
