Multi-mode supermolecular polymerization driven by host-guest interactions.

ABSTRACT: A novel supermolecular self-assembly based on ternary host-guest interaction between cucurbit[8]uril (CB[8]), 1,1'-dimethyl-4,4'-bipyridinium dication (MV) and coumarin derivative was applied for the construction of linear supramolecular polymer with high degree of polymerization in aqueous solution. Accompanied by the introduction of azobenzene on linear ABBA type monomer the supermolecular polymerization is different and the morphology changes from linear to dendritic polymer. The successful supramolecular polymerization of linear and dendritic supramolecular polymers by non-covalent host-guest molecular recognition was confirmed by various characterization methods, such as ¹H NMR spectroscopy, ROESY, transmission electron microscopy (TEM) and dynamic light scattering (DLS) me
