Dual stimuli-triggered dielectric switching and sensing in a host-guest cyanometallate framework

The host-guest hybrid cyanometallate framework (MA)(H2O)[Sr(H2O)(2)-Co(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)].
