Photodimerization behaviour of 1D–3D Zn(ii) coordination polymers with tetrazolyl styrylpyridine

Abstract

The [2 + 2] photodimerization of tetrazolyl styrylpyridine leads to single-crystal-to-single-crystal transformations of four Zn(II) coordination polymers with 1D–3D structures, exhibiting controllable reaction extent, luminescence decrease or blue shift, and a two-step reaction process with a phase transition point.
