Molecular ferroelectrics have gradually aroused great interest in both fundamental scientific research and technological applications because of their easy processing, light weight and mechanical flexibility. Hybrid organic-inorganic perovskite ferroelectrics (HOIPFs), as a class of molecule-based ferroelectrics, have diverse functionalities owing to their unique structure and have become a hot spot in molecular ferroelectrics research. Therefore, they are extremely attractive in the field of ferroelectrics. However, there seems to be a lack of systematic review of their design, performance and potential applications. Herein, we review the recent development of HOIPFs from lead-based, lead-free and metal-free perovskites, and outline the versatility of these ferroelectrics, including piezoelectricity for mechanical energy-harvesting and optoelectronic properties for photovoltaics and light detection. Furthermore, a perspective view of the challenges and future directions of HOIPFs is also highlighted.
分子铁电体因其易于加工、重量轻和机械柔韧性，在基础科学研究和技术应用中逐渐引起了极大的关注。有机-无机杂化钙钛矿铁电体（HOIPFs）作为一类基于分子的铁电体，由于其独特的结构而具有多种功能，已成为分子铁电体研究的热点。因此，它们在铁电体领域极具吸引力。然而，似乎缺乏对其设计、性能和潜在应用的系统综述。在此，我们综述了基于铅、无铅和无金属钙钛矿的HOIPFs的最新进展，并概述了这些铁电体的多功能性，包括用于机械能收集的压电性以及用于光伏和光检测的光电特性。此外，还强调了HOIPFs面临的挑战和未来方向的前瞻性观点。
