In this study, we electrochemically intercalated chiral molecular cations into the layered material MoS₂ to fabricate an artificial organic-inorganic hybrid chiral semiconductor. Structural and electronic changes in the treated samples were evaluated, confirming enhanced conductivity and induced chirality. Under 405 nm circularly polarized light irradiation, distinct photocurrent responses were observed for left- and right-circularly polarized light, suggesting the generation of spin-polarized currents via the circular photogalvanic effect (CPGE), reflecting the unique electronic states of the chiral system.
