Disclosed by the present invention are a substituted 1,3,5-triazine compound, a composition and an application thereof. Provided by the present invention is a 1,3,5-triazine compound represented by formula I. The 1,3,5-triazine compound of the present invention can be used not only as an electron transport material, but also as an electron acceptor material, and can prepare an electron transport layer or can, along with an electron donor material composition, serve as the main material of an electroluminescent device, the electroluminescent device prepared therefrom having the advantages of high efficiency and long service life; furthermore, the 1,3,5-triazine compound is used as an electron transport layer and is simultaneously used as an electron acceptor material and electron donor material composition to construct a light emitting layer, and the prepared electroluminescent device has the advantages of higher efficiency, longer service life, and so on. |
