Thioxanthene-Based Thermally Activated Delayed Fluorescence Emitter Triggered by Magnetic field |
| 초록 |
Thermally activated delayed fluorescence (TADF) is the 3rd generation of OLED emitter. Blue TADF emitters had been numerouslyinvestigated on increasing the efficiency ever since it is first introduced. Here we have developed a deep blue TADF emitter using 9,9-dimethyl-9H-thioxanthene 10,10-dioxide (DMTD) acceptor and a 10H-spiro[acridine-9,9'-fluorene] (SpiroAc) donor. The major TADF Process is practicable by reducing singlet−triplet splitting (ΔEST).However, we have demonstrated new methods to make this process more efficient. Our approach involves the use of magnetic field to access the spin-orbit coupling in the excited molecule and use it as a means of controlling the TADF phenomenon. Our experiments regarding measurement of optical and TADF properties were carried out in solution state and will discuss in poster presentation. |
