The sunlight-driven photosalient effect of a 1D coordination polymer and the release of an elusive cyclobutane derivative†
Abstract
A one-dimensional coordination polymer (1D CP) [Zn(glu)(4-nvp)] (1) [H2glu = glutaric acid and 4-nvp = 4-(1-naphthylvinyl)pyridine] with a paddle-wheel unit [Zn2(O2CC)4] exhibits the photosalient effect under UV as well as sunlight irradiation, resembling the popping of popcorn, along with the release of an elusive cyclobutane ligand.
