Ferroelectric materials, characterized by the reversible switching of spontaneous polarization by an applied electric field, exhibit excellent physical properties including dielectric response, pyroelectricity, piezoelectricity, electro-optics, and nonlinear optical effects, etc. All these physical properties have been widely used for diverse practical applications. In recent years, two-dimensional (2D) organic-inorganic hybrid perovskites have emerged as an important family of ferroelectrics. Benefitting from unique structural compatibility and tunability, this 2D class of ferroelectrics enable the coexistence and/or coupling of multiple functions, which become an ideal platform for the development of new multifunctional candidates. Based on the Curie symmetry principle, this work illuminates the crystallographic symmetry breaking and highlights the source of ferroelectricity in 2D hybrid perovskite ferroelectrics, as well as potential strategies to modulate their photoelectric properties. Finally, we propose the development trend and application prospects of these 2D hybrid perovskite ferroelectric materials.
