Bistable Dynamic Coordination Polymer Showing Reversible Structural and Functional Transformations

Abstract

A bistable dynamic coordination polymer [Ni(pca)(bdc)0.5(H2O)2] having a two-dimensional (2D) zigzag sheet structure is synthesized solvothermally. Topological analysis revealed that the frameworks have an hcb type of uninodal net. The compound exhibits guest specific reversible structural transformations accompanying reversible changes in physical properties driven by inherent flexibility and transformability.
