Organic-inorganic quasi-two-dimensional (q-2D) perovskite compounds have been attracting attention as optical materials because of their excellent light absorption and luminescence properties. By introducing optically active amines to q-2D perovskites, circular polarization properties are expected. In this study, q-2D perovskite nanoparticles were prepared using S- and R-type optically active amines, and their circular polarization properties were evaluated. Symmetric CD signals corresponding to exciton absorption were observed.
