A near-room-temperature organic-inorganic hybrid ferroelectric: [C 6 H 5 CH 2 CH 2 NH 3 ] 2 [CdI 4 ]

An organic-inorganic hybrid compound, [C H CH CH NH ] [CdI ], 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 findin...

Zusammenfassung:An organic-inorganic hybrid compound, [C H CH CH NH ] [CdI ], 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.
