Abstract

Abstract: A novel porous metal–organic framework (MOF) architecture is formed by a neutral amide‐functionalized ligand and copper(II). Upon desolvation, this compound undergoes a dynamic structural transformation from a one‐dimensional (1D) porous phase to a two‐dimensional (2D) non‐porous phase that shows selective uptake of benzene over cyclohexane. The as‐synthesized compound also acts as a visual colorimetric anion sensor for thiocyanate.
