Constructing a photoferroelectric semiconductor by regulating non-covalent interactions through halogen substitution.

ABSTRACT: The advantages of molecular ferroelectrics lie in the "designability" and "multifunctionality", and the molecular-level regulation ability has opened up a brand-new dimension for ferroelectric materials. Non-covalent interactions play a crucial role in the construction of molecular ferroelectrics. However, there remain significant challenges in balancing the strength and reversibility of non-covalent interactions, as well as achieving long-range ordered arrangements. Therefore, a systematic study of non-covalent interactions in the structure is the key to construct high-performance molecular ferroelectrics. Here, we introduced halogenated amines with large dipole moments into adjacent inorganic layers to regulate the non-covalent interactions in the structure, thereby inducing the generati
