Abstract

The organic salt bis(2-chloroethyl)amine hydrochloride shows a sharp switching of its dielectric constant at 320 K. The switching property originates from the dynamic changes of the (2-chloroethyl)ammonium cation between frozen and motional states, corresponding to a structural phase transition.
