Chiral supramolecular assembly of n-conjugated luminophores provides a promising avenue for enhancing circularly polarized lumi-nescence.In this study,we shed light on the impact of π-conjugation length on circularly polarized luminescent performance of the resulting supramolecular assemblies,by designing a tetra-cyanostilbene monomeric compound alongside two dicyanostilbene con-trol compounds.These cyanostilbene-based compounds possess the ability to form chiral supramolecular polymers in toluene,driv-en by a synergistic combination of intermolecular hydrogen bonding and π-π stacking interactions.The extended π-aromatic skele-ton brings bathochromic-shifted fluorescence and enhanced intermolecular stacking capability for the tetra-cyanostilbene com-pound.Consequently,chiral supramolecular assemblies formed by the tetra-cyanostilbene compound demonstrate a remarkable two-fold increase in glum values relative to the assemblies formed by the dicyanostilbene compounds.Overall,this study provides valuable insights into the relationship between n-conjugation length and the circularly polarized luminescent performance ofπ-conjugated supramolecular assemblies.
