Executive Summary : | Chiral optical properties in organic molecules are useful in various applications, such as second harmonic generators, photodetectors, and circular polarized photoluminescence (CPL). However, stacking chiral organic molecules for optoelectronic devices is challenging due to their intrinsic features like poor charge transport, wide band gap, and structural softness. Organic-inorganic hybrid metal halide perovskites (OIMHPs) have been attracting research interest due to their tunable band gap, long diffusion lengths, high absorption coefficients, and low defect densities. Combining OIMHPs with chiral molecules can create promising chiral perovskites that enable efficient CPL photodetectors for next-generation optic and spintronic devices. The proposed project aims to investigate the structure-property relation of low-dimensional lead-free chiroptical perovskites synthesized via reliable, facile methods by intercalating chiral ligands as spacer cations for efficient CPL photodetectors. |
