Enantioresolution and absolute stereochemistry of a photochromic bis(benzo[b]thienyl)ethene compound.
The colored closed-ring isomers of a bis(benzo[b]thienyl) type photochromic diarylethene compound were enantioresolved by chiral column chromatography. The absolute stereochemistry of a (-)633-compound was determined by X-ray crystallography as (S,S). The relationship between the absolute stereostructure and the circular dichroism (CD) spectrum is discussed.
