摘　　要：设计合成了咪唑类二芳基乙烯化合物L,通过1H NMR、13C NMR和元素分析对其分子结构进行了表征,并考察了酸效应对其光致变色性能的影响。结果显示,通过酸效应能够有效调节化合物L的吸收光谱、荧光光谱和热稳定性。化合物L在质子化前后,均表现出良好的光致变色性能,且显示出与众不同的"on to on"的荧光特性。Diarylethene-containing imidazole derivative L was synthesized and characterized by 1H NMR, 13 C NMR and elemental analysis. The effect of acid on photochromic properties of L was investigated. The results show that the absorption spectra, fluorescence spectra and thermal stability of L can be effectively regulated by the acid. In addition, L shows good photochromism before and after the protonation, and the distinctive ＂on to on＂ fluorescence characteristics.
