Title:
SUBSTITUTED 1,3,5-TRIAZINE COMPOUND, COMPOSITION AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/199996
Kind Code:
A1
Abstract:
Disclosed are a substituted 1,3,5-triazine compound, composition and application thereof. The present invention provides a 1,3,5-triazine compound represented by formula I. The 1,3,5-triazine compound in the present invention can be used not only an electron transport material, but also an electron acceptor material. The compound can be used for preparing an electron transport layer or is used in combination with a composition of an electron donor material to serve as the main material of an electroluminescent device, so that the electroluminescent device obtained by preparation has advantages such as high efficiency and long service life. Furthermore, while being used as an electron transport layer, the 1,3,5-triazine compound is used in combination with a composition of an electron donor material as an electron acceptor material to construct a light-emitting layer, so that the electroluminescent device obtained by preparation has advantages such as better efficiency and longer service life.
