Abstract

Herein, we present the self‐assembly and chiroptical properties of enantiomeric bischromophoric molecules consisting of trans‐(1,2)‐cyclohexanediamide as the chiral core and cyanostilbene derivative as the fluorescent chromophores. These enantiomers form diverse organic nanostructures, such as vesicles and two‐dimensional sheets, in non‐polar solvents, exhibiting circularly polarized luminescence (CPL) with a remarkable luminescence dissymmetry factor, |glum|, in solution. Detailed spectroscopic probing reveals the formation of supramolecular conglomerate assemblies from its racemic mixture of monomers due to the chirality mismatch of the core.
