Abstract

The invention discloses triphenylethylene-like structure derivatives and applications thereof. The triphenylethylene-like structure derivatives have a structure shown in the following formula (I): (I). Wherein, A is spirofluorenetriphenylamine and spirofluorenetriphenylamine derivatives with different positions. The triphenylethylene-like derivatives at different sites of the present invention can effectively control the degree of conjugation through site regulation, and obtain non-doped fluorescent devices with different light colors. Compared with commonly used fluorescent guest materials, the use of the present invention The structure of the OLED device in which the material is used as a light-emitting layer can be effectively simplified, the cost is greatly saved, and a high-efficiency fluorescent device can be obtained, which can be widely used in the field of organic electroluminescence.

Description

technical field [0001] The invention belongs to the technical field of organic photoelectric materials, and specifically relates to a triphenylethylene-like derivative and its application. Background technique [0002] Organic electroluminescence is considered to be a new generation of flat panel display technology with excellent development prospects. Compared with inorganic electroluminescent materials, organic electroluminescent materials have the advantages of high luminous efficiency, strong luminous brightness, low energy consumption, low driving voltage, and simple manufacture. Designing and synthesizing organic electroluminescent materials that can meet the requirements of commercialization is attracting widespread attention from all walks of life. [0003] Organic electroluminescent materials are generally divided into singlet fluorescent dyes and triplet phosphorescent dyes. Singlet fluorescent dyes are widely used in fluorescent devices because they can use their...
