| titleOfInvention | A TADF-sensitized fluorescent organic light-emitting diode and preparation method thereof |
| abstract | The invention discloses a thermally activated delayed fluorescence sensitized fluorescence organic light-emitting diode and a preparation method thereof. The light-emitting layer of the fluorescent organic light-emitting diode is composed of a host material, a TADF sensitizer and a fluorescent guest material; the host material is composed of mCBP and PO-T2T was blended according to the weight ratio of 1:1; the TADF sensitizer was Pr-1; the fluorescent guest material was DCJTB. The TADF sensitized fluorescent OLEDs of the present invention use high-energy exciplex as the host and TADF material as the sensitizer. Not only the exciplex host has an intermolecular RISC process and the TADF sensitizer has an intramolecular RISC process, but also the TADF sensitizer has an intramolecular RISC process. The electron acceptor materials in the chemist and exciplex host can also form low-level exciplexes, and the finally obtained fluorescent OLEDs have the characteristics of high efficiency, low efficiency roll-off and good stability. |
