Abstract

See full text

Disclosed are a compound with anthrone and N-containing heterocycle and an application thereof in an OLED. The compound contains anthrone and N-containing heterocycle structure which are both strong electron-withdrawing groups. The compound has a deep HOMO energy level and high electron mobility and is suitable for use as hole blocking materials or electron transport materials; the compound can also be used as a host material for electron-type light-emitting layers; in addition, the compound of the present invention has strong group rigidity, not easily causes crystallization and aggregation between molecules, and has good film-forming property. After the compound of the present invention is applied to an OLED device as an organic electroluminescent functional layer material, the current efficiency, power efficiency and external quantum efficiency of the device are greatly improved; moreover, the compound can improve the service life of the device.
