Unprecedented Richness of Temperature‐ and Pressure‐Induced Polymorphism in 1D Lead Iodide Perovskite
Abstract
<jats:title>Abstract</jats:title><jats:p>Inherent features of metal halide perovskites are their softness, complex lattice dynamics, and phase transitions spectacularly tuning their structures and properties. While the structural transformations are well described and classified in 3D perovskites, their 1D analogs are much less understood. Herein, both temperature‐ and pressure‐dependent structural evolutions of a 1D AcaPbI<jats:sub>3</jats:sub> perovskitoid incorporating acetamidinium (Aca) cation are examined. The study reveals the existence of nine phases of δ‐AcaPbI<jats:sub>3</jats:sub>, which present the most diverse polymorphic collection among known perovskite materials. Interestingly, temperature‐ and pressure‐triggered phase transitions in the 1D perovskotoid exhibit fundamentally different natures: the thermal transformations are mainly associated with the collective translations of rigid polyanionic units and ordering/disordering dynamics of Aca cations, while the compression primarily affects inorganic polymer chains. Moreover, in the 1‐D chains featuring the face‐sharing connection mode of the PbI<jats:sub>6</jats:sub> octahedra the Pb···Pb distances are significantly shortened compared to the corner‐sharing 3D perovskite frameworks, hence operating in the van der Waals territory. Strikingly, a good correlation is found between the Pb···Pb distances and the pressure evolution of the bandgap values in the δ‐AcaPbI<jats:sub>3</jats:sub>, indicating that in 1D perovskitoid structures, the contacts between Pb<jats:sup>2+</jats:sup> ions are one of the critical parameters determining their properties.</jats:p>
