Development of New Fluorescence Emitters with Aggregation-Induced Emission Based on Anthracene Moiety |
| 초록 |
DAD and TAD were synthesized through Suzuki aryl-aryl coupling and Buchwald-Hartwig amination. In film state, DAD showed 388nm and 454nm of UV-Visible absorption wavelength and 546nm of photoluminescence (PL) maximum wavelength. TAD showed 406nm of UV-Visible absorption wavelength and 513nm of PL maximum wavelength. Interestingly, DAD and TAD showed weak PL intensity in solution state, but showed strong PL intensity in film state. This phenomenon called aggregation-induced emission. In non-doped device, DAD showed current efficiency (C.E.) of 18 cd/A and external quantum efficiency (E.Q.E) of 5.20%, respectively. Also, TAD showed C.E. of 16 cd/A and E.Q.E of 5.69%, respectively. |
