The emergence of the chiral-induced spin-selectivity effect offers a new avenue for chiral organic molecules to autonomously manipulate spin configurations, thereby opening up possibilities in spintronics and spin-dependent electrochemical applications. In this study, a promising chiral van der Waals superlattice is synthesized via electrochemical intercalation of chiral molecules into a van der Waals layered material. Multiple tunneling processes within the highly ordered chiral layered structure of chiral TiS2 superlattices result in an exceptionally high spin polarization exceeding 90%. The combination of metallic conductivity and high spin polarization sets the stage for the development of a new generation of CISS materials, enabling a wide range of electron spin-based applications.
