Topology in the chemistry of polymers

Summary

Several groups of oligomers and polymers characterized by a topological structure have been described. Catenanes, rotaxanes and knots as well as their polymers have been presented as fundamental structures having topological bonds. The rotaxane polymers can be considered as starting substances for producing tubular systems. A group of ball-like polymers (dendrimers) shaped topologically is discussed in relation to their low molecular partners: dodecahedrane, fullerenes and fullerene endohedral complexes. Problems discussed concern the scientific interest of the Topological Polymers Laboratory at the ICRI in Warsaw. One of the main directions of studies in this Laboratory is the synthesis of a dendrimer in a set of succeeding cyano-ethylation reactions of amine groups and cycloaddition of dicyandiamide to the formed nitrile groups (Figs. 8 and 9).
