Document Type and Number:

WIPO Patent Application WO/2018/019254

Kind Code:

A1

Abstract:

The present invention discloses a diphenyl ketone-based compound and an application thereof in an organo-electroluminescent device. The compound has the properties of limited intermolecular crystallization, limited clustering, and excellent film-forming characteristic. A rigid radical in a molecule can also improve the heat stability of a material. The compound of the present invention can be applied as a light-emitting layer material for the organo-electroluminescent device. A light-emitting device using the compound has excellent photo-electric performance and can better adapt and satisfy an application requirement of a panel manufacturing company.
