Chiral Cation Doping for Modulating Structural Symmetry of 2D Perovskites

Cation mixing in two-dimensional (2D) hybrid organic–inorganic perovskite (HOIP) structures represents an important degree of freedom for modifying organic templating effects and tailoring inorganic structures. However, the limited number of known cation-mixed 2D HOIP systems generally employ a 1:1...

Zusammenfassung:Cation mixing in two-dimensional (2D) hybrid organic–inorganic perovskite (HOIP) structures represents an important degree of freedom for modifying organic templating effects and tailoring inorganic structures. However, the limited number of known cation-mixed 2D HOIP systems generally employ a 1:1 cation ratio for stabilizing the 2D perovskite structure. Here, we demonstrate a chiral–chiral mixed-cation system wherein a controlled small amount (
