Ferroelectricity and Piezoelectric Energy Harvesting of Hybrid A₂BX₄-Type Halogenocuprates Stabilized by Phosphonium Cations.

ABSTRACT: Perovskite-structured compounds containing organic cations and inorganic anions have gained prominence as materials for next-generation electronic and energy devices. Hybrid materials possessing ferro- and piezoelectric properties are in recent focus for mechanical energy harvesting (nanogenerator) applications. Here, we report the ferroelectric behavior of A₂BX₄-type halogenocuprate materials supported by heteroleptic phosphonium cations. These lead-free discrete Cu(II) halides [Ph₃MeP]₂[CuCl₄] (1) and [Ph₃MeP]₂[CuBr₄] (2) exhibit a remnant polarization (P _r) of 17.16 and 26.02 μC cm^-2, respectively, at room temperature. Furthermore, flexible polymer films wer
