Bismelamines end-functionalized with oligo(p-phenylenevinylene) self-aggregate in nonpolar solvent to form short nanorods by helical π–π stacking. This inherent self-aggregation can be guided to a supramolecular polymerization pathway by complexing with a cyanurate, leading to gel-forming elongated nanotapes lacking the helical sense of the π-conjugated moieties.
