Controlling polymer architecture through host-guest interactions

(Figure Presented) A supramolecular method to control polymer architectures (see picture) is demonstrated with the synthesis of a series of poly(sulfone-amine) samples with various degrees of branching merely by changing the amount of host (β-cyclodextrin) present. Further modification of the polymer chains allows the preparation of condensation polymers with peculiar topological structures, functionalities, and properties.
