Abstract

An organic–inorganic hybrid compound, [C₆H₅CH₂CH₂NH₃]₂[CdI₄], exhibits a reversible ferroelectric phase transition at 301/297 K. Switchable dielectric constant, second harmonic generation, and pyroelectricity were synchronously observed accompanied by the order–disorder phase transition. This finding promotes research on molecular ferroelectrics to search for promising multifunctional switching materials at near room temperature.
