25_17/2004Cover: Polymeric topological isomers, theta-shaped and manacle-shaped polymers, have been synthesized from a polymer self-assembly using a star telechelic poly(THF) having N-phenylpyrrolidinium salt end groups carrying dicarboxylate counteranions. The two constitutional polymeric isomers were subsequently separated by means of a reversed-phase liquid chromatography (RPC) technique. The picture shows that the theta- and manacle-shaped polymers obtainable from linear and from star precursors are distinctive from each other with respect to the position of linking groups within their identical polymer framework, and it demonstrates the ability to place functional groups in specific locations in complex macromolecular topologies.
