Abstract

A Zn(ii) based one-dimensional (1D) coordination polymer (CP), Zn(cis-1,4-chdc)(4-nvp) (1) {cis-1,4-H2chdc = cis-1,4-cyclohexanedicarboxylic acid and 4-nvp = 4-(1-naphthylvinyl)pyridine}, undergoes a solid-state photochemical 2+2 cycloaddition reaction, accompanied by mechanical motion, wherein crystals show swelling, jumping, splitting and bursting upon UV irradiation, whereas the analogous Cd(ii) CP Cd(cis-1,4-chdc)(4-nvp) (2) does not show any such response under UV light, although it undergoes 2+2 photodimerization. The present study can certainly provide the fundamental understanding for designing smart photoactuating materials.
