| Abstract: | 1,2-Bis{5-(2-benzothiazolyl)-2-methyl-6-trifluoromethylthieno3,2-b]thiophen-3-yl}hexafluorocyclopentene possessing high fatigue resistance was synthesized for the first time. Its photochromic and fluorescence properties were studied. The structure of its cyclic form was established by X-ray diffraction analysis. |
