Abstract

The invention relates to a silicious benzanthracene organic electroluminescent material, and a preparation method and application thereof. The invention solves the technical problem that the blue light material in the prior art can not satisfy the requirement of industrialized development. The silicious benzanthracene organic electroluminescent material provided by the invention is an R1 / R2-substituted silicious benzanthracene compound prepared by reacting R1 / R2-substituted amine compound and silicious benzanthracene bromine substitute. Due to the introduction of substituted groups, the material has the advantages of higher solubility, favorable film-forming properties and higher luminescence efficiency, and is suitable for manufacturing an OLED (organic light-emitting diode) device. The material has the characteristics of simple preparation method, low cost and higher yield, and is easy to purify. The organic electroluminescent material can be used as a luminescent material, luminescent main body material or transmission material in an electroluminescent device, and has wide prospects.

Description

technical field [0001] The invention relates to the field of organic photoelectric materials, in particular to a silicon-containing benzanthracene organic electroluminescent material and its preparation method and application. Background technique [0002] After ten years of development, organic electroluminescent devices (OLEDs) have become the most powerful contenders for next-generation flat-panel display devices. Compared with liquid crystal flat-panel displays, organic electroluminescent flat-panel displays have significant characteristics such as active light emission, no angle dependence, good contrast, light, thin, and low energy consumption, and have broad application prospects. The primary colors red, green, and blue are necessary for an effective full-color display. Among red, green and blue three-primary color luminescent materials, green and red materials have reached or approached practical requirements in terms of efficiency and lifespan. In contrast, blue li...
