Paragraph 0045-0046; 0054-0056, (2020/07/21)
The invention provides a thermal activation delayed fluorescence material and an application thereof. The thermal activation delayed fluorescence material has the following structure: a compound taking tris([1, 2, 4] triazole)[4, 3-a: 4', 3'-c: 4'', 3''-e][1, 3, 5] triazine as a receptor core has the property of thermally activated delayed fluorescence, and the receptor has a rigid planar structure, so that the thermal stability of the material is effectively improved; a large torsion angle between a donor unit and an acceptor unit can inhibit intermolecular accumulation; the solubility and the film-forming property are improved; meanwhile, the larger torsion angle can reduce overlapping of molecular front line orbits, so that the lowest excited singlet state-triplet state energy level difference is reduced, triplet state excitons can return to the singlet state through reverse intersystem crossing and finally return to the ground state in a radiation transition mode to emit fluorescence, the exciton utilization rate is increased, and finally the purpose of improving the device efficiency is achieved.
