The organic-inorganic hybrid perovskite (H2hpz)[K(ClO4)3] (H2hpz = diprotonated homopiperazine) exhibits a distinct room-temperature dielectric transition. The dielectric switching at 303 K is associated with an order-disorder transition of the polar guest cation confined in the cage, corresponding to a dynamic change between motional and frozen states.
