摘要

Diisopropylammonium cation based single crystals with different counter anions (F⁻, Cl⁻, Br⁻, I⁻, NO^-₃, and CIO^-₄) were prepared. Their crystal structures and ferroelectric properties were investigated by single-crystal X-ray diffraction spectroscopy, differential scanning calorimetry, and dielectric measurements. The experimental results illustrate that the ferroelectric properties of diisopropylammonium-based single crystals are closely related to the electronegativity and structure of the counter anions. For monoatomic anions, higher electronegativity results in higher polarization and phase-transition temperature of the corresponding molecular–ionic ferroelectrics. The results of density-functional theory (DFT) calculations also support the experimental results.
