<jats:title>Significance</jats:title> <jats:p>Metallosupramolecular π-conjugated amphiphiles have emerged as a building block for supramolecular architectures owing to their interesting luminescence behavior and their propensity to form noncovalent metal–metal interactions. This work represents the first example, to our knowledge, of the alkynylplatinum(II) terpyridine system that can undergo supramolecular assembly into tubular nanostructures. The modulation on the steric bulk of the moieties could control the formation of the designated molecular architectures, ranging from nanotubes to helical ribbons. In addition, the uniqueness of the chromophores has allowed the study of their assembly processes, in which a mechanism of cooperative supramolecular polymerization into nanotubes has been elucidated. This study has provided an in-depth understanding into the supramolecular polymerization that occurs through noncovalent Pt···Pt and π−π stacking interactions.</jats:p>
