| Research Abstract |
A heteroditopic monomer bearing a bisporphyrin cleft and trinitrofluorenone polymerized through a head-to-tail host-guest interaction. Although each of the monomers are connected by non-covalent interactions, the supramolecular polymer chains reptated like a conventional polymer in semi-dilution regime. A tetrakisporphyrin monomer assembled to form supramolecular polymers that were dissociated by competitive guest complexation in solution. Helical morphologies were produced via the supramolecular polymerization in the solid state.[ 60] Fullerene-grafted polyphenylacetylenes were cross-linked by the supramolecular connection generated via the molecular recognition of the[ 60] fullerene moiety and a homoditopic calix[ 5] arene host. The cross-linking increased the molecular weight of the polymer in solution. Nanoparticle-like morphology was obtained from the polymer solution, but the cross-linked polymer generated highly oriented nanostructures in which each of the polymer chains were aligned in a parallel fashion
