Development of azasiline-based materials for thermally activated delayed fluorescence |
| 초록 |
Recently, the azasiline unit was introduced as a donor in thermally activated delayed fluorescence emitters to realize efficient blue fluorescence for organic light emitting diodes. The donor unit of azasiline was utilized in blue fluorescent emitters in order to exploit the full potential of this unique moiety. The addition of a phenyl bridge to the D–C–A type materials demonstrated an increased horizontal dipole ratio compared to that of DTPDDA. And we synthesize the D–A–D type two materials using carbonyl and sulfone units as acceptors. 100% internal quantum efficiency in fluorescent organic light emitting diodes (FOLEDs) became an achievable goal upon implementing efficient thermally activated delayed fluorescence (TADF) materials which enable reverse intersystem crossing (RISC). |
