A Solid State Zwitterionic Plastic Crystal With High Static Dielectric Constant.

ABSTRACT: Solid materials with a high dielectric constant have a wide range of applications in the energy storage field. In this research, an imidazolium-based zwitterion is designed, synthesized, and confirmed to have a plastic crystal phase based on the following experimental and computational evidence: (i) the presence of long-range order with weak intermolecular forces and competing attractive-repulsive interactions along different crystallographic directions; (ii) the observation of more than one endotherm on heating including a solid-solid phase transition at T_s-s = -26 °C and melting of the plastic crystal at T_m = 72°C; (iii) a low entropy of fusion at melting (2.1 JK^-1mol^-1); (iv) a strongly anisotropic morphology; (v) relatively fast dynamics orig
