Abstract

The invention discloses an anthracene derivative and its preparation method and application. The anthracene derivative has a chemical structure shown in formula (I) or formula (II); the anthracene derivative provided by the invention utilizes the highly efficient fluorescence quantum efficiency of anthracene As a bridge, with the help of the electron-withdrawing and electron-donating properties of the cyano group and the electron-donating properties of the fluorene group, the carrier injection and transport are more balanced, which is conducive to improving the performance of the device; at the same time, the fluorene group with a large steric hindrance twisted structure improves the aggregation state of the solid film High fluorescence quantum efficiency, and efficient blue light emission in organic solvents. The invention also provides a preparation method of the anthracene derivative, and its application in the preparation of blue light-emitting materials, light-emitting devices or smart materials.

Description

technical field

[0001] The present invention relates to the technical field of organic luminescent materials, more specifically, to an anthracene derivative and its preparation method and application. Background technique

[0002] Organic light-emitting diodes (OLEDs) have huge applications in flat panel displays, smartphones, and solid-state lighting due to their light weight, good flexibility, wide operating temperature range, short response time, high brightness and contrast, and wide viewing angles. potential. Among them, OLED devices are of decisive significance to display technologies such as full-color display and solid-state lighting. So far, although there have been many reports on anthracene-based light-emitting materials based on small-molecule organic electroluminescent devices, due to the large planar nature of anthracene molecules, it will form π-π stacking in the aggregated state, resulting in its fluorescence being quenched. off, thereby reducing the effici...
