摘要：

An efficient protocol for the synthesis of oxadisilole-fused phenanthridines and dioxatrisilole-fused phenanthridines by aza Diels-Alder reactions and dehydrogenation aromatization reactions of benzyne with N-benzylideneanilines in good yields at room temperature. The photophysical, redox and thermal properties of oxadisilole-fused phenanthridines have been determined. The oxadisilole-fused phenanthridines show potential applications used as blue emitters for OLED due to their high fluorescence quantum yields and thermal stabilities. (C) 2015 Elsevier Ltd.
