Outline of Final Research Achievements

Some photochromic diarylethene molecules formed polar crystal structures belonging to non-centrosymmetric space groups. X-Ray crystallographic analysis revealed that photoisomerization of the diarylethene molecule induces reversible deformation of the crystal lattice of the polar crystal. Diarylethene molecules having thienopyridine or quinoline groups formed cocrystals with other molecules via intermolecular hydrogen bonds or halogen bonds, which would be utilized as a non-covalent interaction for controlling the crystal structure of diarylethene.
