A kind of high-efficiency blue-green to orange-red photothermal activated delayed fluorescent material, preparation method and application thereof |
| abstract |
The invention relates to a high-efficiency blue-green to orange-red photothermal activation delayed fluorescent material, as well as a preparation method and application thereof. The invention solves the problems of the prior art, and through ingenious molecular design, a series of thermally activated delayed fluorescent materials with lower single-triplet state energy level difference, high luminous efficiency and fast reverse intersystem crossing constant are synthesized. Structural fine-tuning was achieved to cover the spectrum from blue-green to orange-red. Their structures were confirmed by hydrogen NMR and mass spectrometry analysis, and then their photophysical properties were studied in detail. Finally, a series of high-performance OLEDs were prepared by applying these light-emitting TADF materials to the light-emitting layer. Application prospects and economic value. |
