Abstract

The invention discloses a luminescence compound of double-vinyl anthracene. The general structure formula is as follows: wherein, R1 is 2-thienyl or phenyl. The compound of the invention is mainly applied in organic electroluminescent displayer, can be directly used as a luminescence layer or used as a doping for making a luminescence layer function.

Description

technical field [0001] The invention relates to a bisvinyl anthracene compound, which belongs to organic electroluminescent materials and is mainly used in organic electroluminescent displays. Background technique [0002] The phenomenon of applying a voltage to an organic substance to induce a current to emit light is called organic electroluminescence (OEL). The organic substance is called an organic electroluminescent material, and a display device made of this material is called an organic electroluminescent display (OLED). A thin film of luminescent material is added between the flat electrodes to form a flat panel display. [0003] The light-emitting materials used in organic electroluminescent displays are divided into polymer and small molecule materials according to the type; according to the light-emitting color, they are divided into blue light, green light, red light, yellow light, orange light and other materials. Anthracene compounds have high quantum efficien...
