Crystal structure of 4-(2-(benzo[b]thiophen-2-yl)-3,3,4,4,5,5-hexafluorocyclopent-1-en-1-yl)-1,5-dimethyl-1H-pyrrole-2-carbonitrile, C20H12F6N2S

“…Up to date, scienctists have designed and synthesized many new diarylethenes. It is reported that some of them can exhibit the properties of photochromism in solid state and in solution [18]. However, some of them cannot show the photochromism in solid state, but they can represent good photochromism characteristics in solution [19].…”

Structure of 7-(3,3,4,4,5,5-hexafluoro-2-(2-methylbenzo[b]thiophen-3-yl)cyclopent-1-en-1-yl)-8-methylquinoline, C24H15F6NS

“…The result demonstrated that the photochromic characteristics of diarylethenes strongly depend on the kind of the heteroaryl moieties and their substituents [18,19]. Some research reported found that part of them can exhibit the properties of photochromism in solid state and in solution [20]. However, some of them cannot show the photochromism in solid state, but they can represent good photochromism characteristics in solution [21].…”
