Photochromic dihetarylethenes 6.~* Photochromic derivatives of thieno3,2-bthiophene

摘要

1,2-Bis{5-(2-benzothiazolyl)-2-methyl-6-trifluoromethylthieno3,2-bthiophen-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 estabihsed by X-ray diffraction analysis.
