抄録
The compounds that undergo photochromic reaction in the crystalline-state are rare and their reaction dynamics are not well characterized as a result of the low degree of interconversion ratios and/or instability of the photo-generated isomers in the solid phase. We have recently found that a rhodium Binuclear complex [ (RhCp*) 2 (μ-CH2) 2 (μ-O2SSO2) ] (Cp*=η5-C5Me5) having a photo-responsive dithionite group (μ-O2SSO2), undergoes an essentially 100% reversible crystalline-state photochromism upon interconversion to [ (RhCp*) 2 (μ-CH2) 2 (μ-O2SOSO) ] . Taking an advantage of this unique full reversibility, we have investigated the dynamics of the system by using stepwise single crystal diffraction and variable-temperature solid-state NMR technique. The stereospecifc oxygen-atom rearrangement process of the dithionite ligand and reorientational motion of the Cp* ligands, which are coupled to the photochromism, are presented.
