A kind of anthracene derivative and its preparation method and application

Abstract

The invention discloses an anthracene derivative and its preparation method and application. The anthracene derivative uses anthracene as a "bridge" and uses (4-bromophenyl)(3-phenylimidazo[1,2-a] Pyridin-2-yl)methanone is used as an acceptor, and the adjustment of absorption and emission spectra is realized by introducing a suitable electron donor, and the construction of a donor-acceptor structure regulates the LUMO and HOMO energy levels, which is conducive to the transmission of balanced carriers, effectively Lower the injection barrier for holes and electrons. The anthracene derivative has a very distorted structure, can inhibit the π-π stacking between molecules, improve the fluorescence quantum yield, and can be used to prepare light-emitting materials and organic electroluminescent devices.

Description

An anthracene derivative and its preparation method and application technical field The present invention relates to the field of organic light-emitting materials, more particularly, to a kind of anthracene derivative and preparation method and application thereof use. Background technique [0002] The organic light-emitting diode (OLED) is light in weight, good in flexibility, wide in operating temperature range, short in response time, bright in With the advantages of high brightness and contrast, and wide viewing angle, it has huge applications in the fields of flat panel display, smart phone and solid-state lighting. Use potential. [0003] The luminescent material is the substance responsible for emitting light in the OLED device, so the luminous efficiency, luminescent lifetime and Properties such as emission color can affect the performance of OLED devices. As a light-emitting material in OLED, it should have the following conditions Components: 1) have high ...
