Abstract
The invention relates to a high-performance sky blue thermally activated delayed fluorescent material, manufacturing method thereof, and application thereof, which solves the problems of the prior art. Through clever molecular design, a series of sky-blue thermally activated delayed fluorescent materials with less singlet-triplet energy level difference, high luminous efficiency, and fast-rate reverse intersystem crossing constant were synthesized, while fine-tuning of the structure and spectrum thereof were realized.
