Abstract

The invention discloses an anthracene derivative. The structural formula of the anthracene derivative is shown in the specification. The anthracene derivative has the beneficial effects that the branch of a triazole derivative is introduced into the main structure of 9,10-bis(beta-naphthyl)anthracene, so that the conjugacy is enhanced to a great extent and the obtained anthracene derivative has relatively high fluorescence quantum efficiency.

Description

technical field [0001] The invention belongs to the technical field of electroluminescent materials, and relates to an organic electroluminescent material, in particular to an anthracene derivative and a preparation method thereof. Background technique [0002] Organic electroluminescence (organic electroluminescence) refers to the light-emitting phenomenon of small organic molecules or polymer films under current injection. Displays made according to this light-emitting principle are OLEDs (organic light-emitting devices). Since C.W.Tang et al. of Eastman Kodak Company in the United States successfully prepared the first OLED device with good performance in 1987, organic electroluminescent displays have made breakthroughs and entered a new stage of development. Compared with traditional display technologies, OLEDs have many advantages such as full solid state, active light emission, high contrast ratio, ultra-thin, low power consumption, no viewing angle limitation, fast re...
