The allomorphism of a photochromic diarylethene
Tetrahedron Letters Pergamon 44(2003)1011-1014，-0001，（）：
The photochromic diarylethene, 1, 2-bis (2-methyl-5-(2,2 -dicyanovinyl)-thien-3-yl) perfluorocyclopentene (1a), was synthesized by a novel method. Two kinds of single crystals of the compound were obtained depending on the different recrystallization conditions and their structures were determined by X-ray crystallographic analysis. Allomorphism of the photochromic diarylethene was discovered. The compound underwent a photochromic reaction both in solution and in the single crystalline phase of the anti-parallel conformer.
