Significant research has been conducted on molecular ferroelectric materials, including pure organic and inorganic compounds; however, studies on ferroelectric materials based on coordination metal complexes are scarce. Ferroelectric materials based on coordination metal complexes have tunable structures and designs, with coexistence or synergy between the ferroelectric behavior and magnetic properties. Compared to inorganic compounds, few coordination metal complexes exhibit coupling between the magnetic and dielectric properties. Coordination metal complexes with strong coupling between the magnetic and dielectric properties exhibit dielectric permittivity variations under external magnetic fields. Therefore, they have attracted substantial interest for their potential use in magnetoelectric devices. In this review, we discuss recent advances in coordination metal complexes, that exhibit coupled magnetic functionalities and ferroelectricity or dielectric properties, including single-molecule magnets, electron delocalization systems, and external stimuli responsive compounds.
已经有大量研究关注于分子铁电材料，包括纯有机和无机化合物；然而，基于配位金属配合物的铁电材料的研究却很少。基于配位金属配合物的铁电材料具有可调节的结构和设计，其铁电性能和磁性能共存或协同。与无机化合物相比，配位金属配合物中很少有表现出磁电性能之间的耦合。具有磁电性能强耦合的配位金属配合物在外磁场下表现出介电常数的变化。因此，它们在磁电器件中的潜在应用引起了人们的极大兴趣。在这篇综述中，我们讨论了最近在配位金属配合物方面的进展，这些配合物表现出耦合的磁功能和铁电性或介电性能，包括单分子磁体、电子离域体系和对外界刺激响应的化合物。
