| Outline of Final Research Achievements |
In order to develop high-performance ambipolar light-emitting transistors, some novel heteroaromatic compounds bearing furan moieties as electron-donating units and pyradine or quinone moiety as electron-accepting unit were synthesized and their solid-state structure and properties have been examined. Two regioisomer with respect to the orientation of fused furan rings were studied. Unfortunately, charge mobilities of these samples were observed to be low due to unfavorable thin-film structure. Nevertheless, they demonstrated unexpectedly high fluorescence quantum yields in solid state, which is known as aggregation-induced emission, AIE. The observation of AIE should arise from either enhanced excimer emission or suppression of molecular motion in solid state.
