| Abstract: | A series of bisthienylethenes containing imidazole and imidazolium derivatives have been prepared and the products have been characterized by means of NMR and MS. Their photochromic and fluorescent switch properties have been investigated by UV-vis absorption spectra and fluorescence spectra. The fluorescent emissions of these kinds of photochromic compounds can be simply modulated by varying the imidazole groups, which shows that these compounds may have potential application in the design of fluorescent photochromic materials. |
