The present invention provides a star-shaped light-emitting material with resorcinol calixarene (Calix[4]resorcinarene, CRA) as a core and its application in organic electroluminescent devices. The compound has a simple synthesis method and reaction conditions. Mild and high yield. In particular, the core CRA has eight highly reactive sites, which can be attached to eight functional groups, and the corresponding functional compounds have good film-forming properties, solubility and high thermal stability. The compounds of the present invention are applied to organic electroluminescent devices as light-emitting layer materials, and excellent device performance can be obtained. |
