Dual stimuli-triggered dielectric switching and sensing in a host–guest cyanometallate framework†
Abstract
The host–guest hybrid cyanometallate framework (MA)(H2O)[Sr(H2O)2Co(CN)6] (1; MA = methylammonium) shows thermally and chemically triggered dielectric switching and sensing via a temperature-driven phase transition and a water-driven reversible structure transformation between 1 and its dehydrated form (MA)[SrCo(CN)6].
