Single-crystal-to-single-crystal transformation of an anion exchangeable dynamic metal-organic framework

Abstract

A three dimensional (3D) cationic Metal-Organic Framework (MOF) has been fabricated from a neutral N-donor ligand and Cd(ClO4)2. The cationic MOF shows guest triggered inherent dynamic behaviour at room temperature. A single-crystal-to-single-crystal (SCSC) transformation experiment enabled the guest dependent structural dynamism to be well understood. The framework also displays facile anion exchange behaviour and anion dependent structural dynamism.
