| titleOfInvention | A seven-membered ring thermally activated delayed fluorescent material and preparation method thereof, and organic light-emitting device |
| abstract | The invention discloses a seven-membered ring thermally activated delayed fluorescent material, a preparation method thereof, and an organic light-emitting device, wherein the general chemical structure of the seven-membered ring thermally activated delayed fluorescent material is: Wherein, Ar 1 -Ar 4 are independently selected from benzene, thiophene, furan, pyridine or substituted above-mentioned aryl or heteroaryl, and R 1 -R 12 are independently selected from hydrogen, deuterium, cyano or alkyl chain One of X is selected from hydrogen, deuterium, halogen, cyano, alkyl chains or benzene, thiophene, furan, carbazole, pyridine, quinoline, isoquinoline, and substituted aryl or heteroaryl groups as described above. The invention can effectively improve the stacking between materials through the introduction of the seven-membered ring, reduce the triplet quenching of the molecules, reduce the efficiency roll-off, and improve the stability and working life of the device; at the same time, the unique boron-nitrogen multiple resonance structure gives The material has a narrow fluorescence emission spectrum and a high external quantum efficiency value. |
