Organic–inorganic metal halides (OIMHs) have attracted great interest in the design of various functional materials due to their advantages easy processability, rich structural diversity, and assembly flexibility. However, rational control stacking patterns OIMHs for regulation has been a long-standing challenge. Particularly, little is known about intrinsic relationship between dimensions dielectric response at molecular scale. Here, we investigated modulation effect cationic halogen engineering (N,N-dimethylethanolamine)PbBr3 on stacking, as well its impact thermal, electrical, optical physical properties. Halogen brings varied from one-dimensional (1D) hexagonal perovskite structure two-dimensional (2D) layered an interlocking 1D chain structure. These attributes demonstrated be closely related interactions crystal lattice, leading variation sequential increase phase transition temperature differences response, with similar bandgaps that are mainly determined by inorganic frameworks. This study offers new insights into performance optimization organic–inorganic hybrids.
