摘要:

通过简单的Wittig反应合成了一个荧光化合物9,10-二(N-苯基吲哚-3-乙烯基)蒽(IA-Ph); 通过核磁共振和质谱对其结构进行了确认; 利用荧光发射光谱和紫外吸收光谱对其光物理性质进行了表征. 结果表明, 化合物IA-Ph兼具聚集诱导荧光(AIE)和压致荧光变色性质, 在相同浓度下, 该化合物在THF/H2O(体积比1∶9)混合溶液中的荧光强度比在纯四氢呋喃(THF)溶液中增加了12倍, 具有明显的AIE效应. 通过简单而有效的机械力研磨, 化合物可以从初始的发绿光转变为研磨后的橙红光, 光谱红移约68 nm; 而且在加热或溶剂熏蒸条件下, 化合物的颜色可以回复到起始的绿光, 具有完全可逆性.

Abstract:

A fluorescent compound 9,10-bis(N-phenylindole-3-vinyl) anthracene(IA-Ph) was obtained by a simple Wittig reaction. The structure of IA-Ph was confirmed by nuclear magnetic resonance and mass spectrometry. The photophysical properties of IA-Ph were characterized by fluorescence emission spectrum and ultraviolet absorption spectrum. It was found that IA-Ph has both aggregation-induced fluorescence(AIE) and piezofluorochromic(PFC) properties. Compared with the fluorescence intensity in pure tetrahydrofuran(THF) solution, the fluorescence intensity of IA-Ph in the mixed solution with V(THF)∶V(H2O)=1∶9 was increased by 12 times, showing an obvious AIE effect. By simple mechanical grinding, the compound could be transformed from initial green light to an orange-red light with a spectral red shift of 68 nm. Under various external stimuli, the compound IA-Ph could change reversibly between green and orange-red fluorescence.
