Enhancing switchable dielectric property for crystalline supramolecular rotor compounds by adding polar components†
Abstract
Two new compounds were obtained by assembling the [(2-methoxy-5-nitro-anilinium)(18-crown-6)]+ cation with non-polar PF6− and polar SO3CF3− anions, respectively. Benefiting from its polar anion, the SO3CF3− compound reveals a more significant dielectric switching behaviour during phase transition, demonstrating an effective strategy to enhance the dielectric property by adding polar components.
