characterized. The compound exhibits remarkable aggregation-induced emission phenomenon and its single crystal shows a blue emission with fluorescent efficiency as high as 45%. Based on its aggregation state behavior, multiple applications towards exploring its lasing, fluorescence switching and electroluminescence properties were realized. Amplified spontaneous emission (ASE) was observed from the crystal and
特吡啶取代的氰基茂苯衍生物(Z)-2-(4'-([[2,2':6',2''-三联吡啶] -4'-基)-[1,1'-联苯] -4-基合成并表征了)-3-苯基丙烯腈(CNSTPy)。该化合物表现出显着的聚集诱导发射现象,并且其单晶显示出蓝色发射,其荧光效率高达45%。基于其聚集态行为,实现了探索其激光,荧光转换和电致发光特性的多种应用。从晶体中观察到放大的自发发射(ASE),并通过可变泵浦剥离法进行了验证,阈值为〜1.5 mJ cm -2。伴随不同分子聚集结构形成的质子化/去质子化过程导致明显的蓝色和黄色发射。另外,该分子还显示出适度的电致发光性能。
