Thermally-activated delayed fluorescence green light polymer material and preparation method therefor |
abstract |
Provided are a thermally-activated delayed fluorescence green light polymer material and an organic electroluminescent device thereof. The thermally-activated delayed fluorescence green light polymer material uses boron as a structural basis, and the overall charge transfer strength is adjusted by means of different electron donating units. A series of green light thermally-activated delayed fluorescence materials having low single triplet energy level differences, high luminous efficiencies and rapid reverse inter-system crossing constants are synthesized. At the same time, the electron-donating capabilities of electron donating units are fine-tuned so as to fine-tune a spectrum. |
