Selective pyridine recognition by an imidazole dicarboxylate-based 3D cadmium(ii) MOF†
Abstract
One new 3D coordination polymer (1) composed of left- and right-handed helices containing [Cd8(p-ClPhHIDC)12(4,4′-bipy)6] cages shows selective pyridine recognition, with a visual colour change from pearl to pink under ultraviolet irradiation.
