Curved- aromatics such as buckybowls, -bent porphyrin derivatives, norcorroles, and pyrroles are particularly attractive compounds that exhibit different characteristics on concave and convex surfaces. For example, in the case of buckybowl corannulene, Aida et al. demonstrated that chaingrowth supramolecular polymerization proceeds in methylcyclohexane (MCH) through intermolecular hydrogen-bonding networks at the side chains of the central corannulene core. In contrast, Würthner et al. reported that self-assemblies of naphthalimide-annulated corannulene occur in MCH, toluene, CCl4, and tetrachloroethane. These results imply that corannulene can effectively induce supramolecular polymerization by introducing appropriate side chains on the central core. Only a pristine buckybowl appears hard to form a supramolecular polymer, most likely due to the shallow bowl depth of corannulene (0.87 Å) that allows for fast bowl-to-bowl inversion in the solution (see Figure , top); hence, discovering a buckybowl "seed" still faces a significant challenge.
