| Research Abstract |
A novel effective means to construct a variety of novel cyclic and multicyclic polymer topologies, including those possessing beta-, gamma- or delta-graph constructions, were developed based on an electrostatic self-assembly and covalent fixation (ESA-CF) protocol, where polymer self-assemblies comprised of linear or branched telechelic precursors having cyclic ammonium salt groups accompanying pluricarboxylate counteranions were employed as key intermediates. The ESA-CF process was also combined with such effective linking chemistry as metathesis condensation (clip) and alkyne-azide addition (click) reactions to afford complex cyclic and multicyclic polymer architectures. By making use of these precisely designed topological polymers, unusual properties and functions were disclosed based on their cyclic and multicyclic topologies, i.e., topology effects, unattainable either by linear or branched counterparts.
