Azobenzene dimer 1 has been previously shown to form chiral nanorings in nonpolar solvents. In this study, azobenzene chromophores are replaced with oligo(p-phenylenevinylene) (OPV). The resulting OPV dimer 2 was shown to form a small number of nanorings, and other assemblies were extended fibrils due to stronger pi-pi stacking interaction.
