Abstract

The invention discloses an aggregation-induced emission luminescent material with circular polarization luminescent and thermally activated delayed fluorescence emission performance, and a preparationmethod and applications thereof. According to the preparation method, molecular design is adopted to synthesize the organic luminescent material with CPL, TADF, and AIE performance; regulation of material aggregation-induced emission, thermally activated delayed fluorescence emission, and circular polarization emission performance can be realized through changing electronic donor groups and chiral groups. The synthesis method and purifying technology of the aggregation-induced emission luminescent material with both circular polarization luminescent and thermally activated delayed fluorescence emission performance are simple; yield is high; the preparation method is suitable for large scale production; and organic electroluminescent devices prepared from the aggregation-induced emission luminescent material with circular polarization luminescent and thermally activated delayed fluorescence emission performance are high in luminance, internal quantum efficiency, and external quantum efficiency, and practical requirements are satisfied.

Description

technical field

[0001] The invention relates to the field of organic luminescent materials, in particular to an aggregation-induced luminescence material with circularly polarized luminescence and thermally activated delayed fluorescence emission, and a preparation method and application thereof. Background technique

[0002] Organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) have unique advantages such as quick response, wide viewing angle, rich colors, light and thin volume, self-illumination and bendable, rollable and even foldable, so they are called the most potential next-generation technology. This generation of display technology is expected to be widely used in electronic products such as mobile phones, TVs, tablet computers, VR (virtual reality, head-mounted displays) and wearable smart devices. In view of its huge economic and social benefits, OLED display technology has been highly valued by academia, industry and even the governments of various...
