- 中文摘要: The single-crystal-to-single-crystal (SCSC) ERZ photoisomerization of TA in the supramolecular solid CECR-[Zn(TA)2(bpy)]-H2O (CECR = C-ethylcalixresorcinarene, HTA = tiglic acid, and bpy = 2,2¢- bipyridine, is induced by 458 nm light, indicating a red-shift of the photo-active wavelength on introduction of the aromatic bpy ligand compared with the previously studied reaction of CECR-[Zn(TA)2(H2O)2]· 4H2O. Theoretical calculations show that the initial excitation involves the bipyridyl ligand, which acts as an intramolecular photosensitizer for the isomerization process. The reaction is topotactic and illustrated by photodifference maps.
