A thermally activated delayed fluorescence green light polymer material and preparation method thereof |
| abstract |
The invention provides a thermally activated delayed fluorescence green light polymer material and an organic electroluminescence device thereof. The thermally activated delayed fluorescence green light polymer material is based on boron as a structure, and the overall charge transfer is adjusted through different electron donating units. Strong and weak, a series of green light thermally activated delayed fluorescent materials with low single triplet energy level difference, high luminous efficiency and fast reverse intersystem crossing constant were synthesized, and at the same time, the fine-tuning of the electron-donating ability of the electron-donating unit was realized. Spectrum fine-tuning. Using the thermally activated delayed fluorescence green light polymer material as the light-emitting layer can improve the light-emitting efficiency of the device, and the performance of the light-emitting device is more stable. |
