The open form of a bisthienylethene with two phenanthroline groups at both ends of the molecule formed, upon the addition of oxalic acid, a sudden precipitation in solution. UV irradiation to the suspension induced dissolution of the precipitate together with the coloration of the solution. The chemical structure of the precipitate was investigated by low-coherence DLS, DOSY, SEM, powder XRD, and...
A novel diarylethene having a 1,10-phenanthroline unit at each end of the molecule has been synthesized. Among the metal ions, it formed a stable complex with Cu(I) ions in acetonitrile. Rational structures of the Cu(I) complexes of the colorless and the photo-generated blue form have been given by PM3 semiempirical molecular orbital calculations to be 2:2 cyclic complexes for both isomers, with the...
