Abstract

The invention provides an electroluminescent material, a preparation method of the electroluminescent material, and a light-emitting device. An anthracene group and a triphenyl phosphine oxide group are selected, wherein anthracene group-containing molecules have an excellent light-emitting characteristic; two triphenyl phosphine oxide groups electron deficiency are added to the 6th position and the 13th position of the anthracene group; and non-coplanar conformation effectively prevents filling of close molecules in a solid state, and prevents excimer formation and fluorescence quenching, sothat the electroluminescent material which can emit blue light and is high in luminous efficiency is realized, the preparation method of the electroluminescent material is realized, and the light-emitting device is realized.

Description

technical field [0001] The present application relates to the display field, in particular to an electroluminescence material, a preparation method of the electroluminescence material and a light emitting device. Background technique [0002] In the prior art, organic light emitting diodes (Organic Light Emitting Diodes) have self-luminous properties, and the materials that dominate their luminescence are mainly electroluminescent materials. However, the low luminous efficiency of current electroluminescent materials often leads to organic light emitting diodes Therefore, it is necessary to provide an electroluminescent material with high luminous efficiency, a preparation method of the electroluminescent material, and a light-emitting device. Contents of the invention [0003] The present application provides an electroluminescence material with high electroluminescence efficiency, a preparation method of the electroluminescence material and a light emitting device.
