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.
