New Blue Thermally Activated Delayed Fluorescence Emitter Adopting a Spiro Fragment as a Donor |
| 초록 |
Thermally activated delayed fluorescence (TADF) is the 3rd generation of OLED emitter. Blue TADF emitters had been numerously investigated 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. DMTD-SpiroAc has twisted plane between donor and acceptor and also donor itself by spiro part, resulting in reduced of singlet−triplet splitting (ΔEST) by separation of HOMO and LUMO portion. We have summarized our experiments regarding measurement of optical and TADF properties for comparison with other emitters that have similar structures with same acceptor but different donors. |
