Ultimate diastereoselectivity in the ring closure of photochromic diarylethene possessing facial chirality.
A bisthienylethene with hitherto unprecedented facial chirality imposed by a triethyleneglycol bridge on a thiophene ring was synthesized and its photochromic ring closure was shown to occur with 100% diastereoselectivity upon UV-light irradiation.
