Abstract A series of new functionalized 2,3,4,5-tetraphenylsiloles were successfully synthesized in good yields by hydrosilylation reaction of 1-methyl-2,3,4,5-tetraphenyl-1H-silole with p-ethynyl benzene derivatives. This synthesis provides a convenient method of introducing reactive electron-withdrawing or electro–donating groups into siloles. All new siloles show aggregation-induced emission (AIE)
摘要 通过1-甲基-2,3,4,5-四苯基-1H-silole与对乙炔苯衍生物的氢化硅烷化反应,成功合成了一系列新型功能化2,3,4,5-四苯基siloles,收率良好。这种合成提供了一种将反应性吸电子或供电基团引入硅酮的便捷方法。所有新的 silole 都表现出聚集诱导发射 (AIE) 效应。图形概要
