Polymeric Building Blocks for Supramolecular Complexation with Cucurbit8uril

摘要

Supramolecular complexation using strong and directional noncovalent interactions has been widely exploited in recent years to develop new, interesting and dynamic materials both in solution and in the bulk.' The functionalization of polymers with multiple hydrogen bonding arrays' or metal complexation powerfully demonstrates the propensity for supramolecular systems to overcome problems associated with traditional covalent polymeric systems such as lack of responsiveness to environmental stimuli.' The majority of the literature in this field, however, has focused on systems relegated to apolar organic solvents in the case of hydrogen bonding arrays, requiring of metals in the case of metal-ligand complexation, or the use of only two components in host-guest complexation in water using, for example, members of the cyclodextrin family.
