Abstract

Chiral organic-inorganic hybrid perovskites (OIHPs) are inversion-asymmetric and have many remarkable properties, including circular dichroism, optical rotation, nonlinear optics, and second-harmonic generation (SHG). Although chiral molecules are responsible for chiroptical properties, they are generally not expected to influence the crystallization of OIHPs. Here, we find that OIHPs synthesized with pristine S- and R-molecules crystallize as 1D perovskites, whereas those synthesized with the racemic molecule crystallized as 2D perovskites. Single crystal X-ray diffraction reveals that the structure change is related to the differing packing of chiral molecules versus racemic ones in OIHPs. Furthermore, we demonstrate that chiral OIHPs containing the S- or R-ligands could be applied in circularly polarized light detectors.
