Progress in chiral organic ferroelectrics

Chiral organic ferroelectrics exhibit advantages including portability, flexibility, and biocompatibility, thereby offering novel solutions for emerging applications such as flexible electronics and implantable medical devices. With the fast development of materials science and technology, this field has advanced from "blind exploration" to the "precision design" of chiral organic ferroelectric materials, significantly accelerating the discovery of high-performance candidates. This review aims to systematically elucidate the dual roles of chirality in chiral organic ferroelectrics: polarity induced by symmetry breaking and dynamic response regulated by topological protection. It thoroughly analyzes the classification and synthesis strategies of various chiral organic ferroelectric systems along the entire "structure-mechanism-performance" chain, aiming to offer a whole picture of this new field.
