Abstract

According to the benzoxanthene organic compound, the electroluminescent device and the display device provided by the invention, the compound can be used as a main body material of an OLED (Organic Light Emitting Diode) luminescent device, so that the OLED luminescent device has relatively low driving voltage and relatively high current efficiency.

Description

technical field [0001] The invention belongs to the field of electroluminescence, and relates to a benzoxanthene organic compound, an electroluminescence device and a display device. Background technique [0002] Currently, organic electroluminescence (OLED) has become a mainstream display technology, and correspondingly, various new OLED materials have also been developed. As the main material of blue light, it is mainly a compound obtained by substituting the 9 and 10 positions of anthracene with aromatic groups, and the aromatic groups mainly include benzene, naphthalene, anthracene, dibenzofuran, dibenzothiophene, and benzodibenzofuran , Benzodibenzothiophene and other groups. Such as CN101628847A, CN101628847A, TW200840110A, CN1914293A, CN101679855A, etc. [0003] CN104418831A discloses a new type of blue-light host material in which benzoxanthene is connected to the 9-position and 10-position of anthracene. However, its various properties need to be improved, especia...
