Homochirality in life is one of the most unique characteristics across multiple length scales. Such prevailing single chirality has been attributed to symmetry breaking occurring in the racemic at the prebiotic stage. Circularly polarized light (CPL) has been considered a possible origin that has inherent chirality. Here, we present how the chiral information encoded in CPL can be transferred and amplified to the supramolecular polymers over the molecular scale, and further discuss the efficiencies of light-matter interaction depending on the structures of monomers resulting in different supramolecular helicities. We will show the emergence of supramolecular chirality can be enhanced and diminished by interacting with molecular chirality and CPL in a constructive and destructive way during the early stage of polymerization. Our findings will provide insights into the mechanism of photon-to-matter chirality transfer in supramolecular polymerizations and the design of chiroptic materials.
