We report the formation of a novel class of supramolecular miktoarm star polymers via cyclodextrin host-guest chemistry. Reversible addition fragmentation chain transfer polymerization from difunctional guest- or alkyne-containing chain transfer agents and copper(I)-catalyzed azide-alkyne cycloaddition leads to host-and guest-containing acrylamido polymers, namely poly(N,N-dimethylacrylamide) and poly(N,N-diethylacrylamide). Subsequently, a supramolecular miktoarm star polymer was formed and characterized via dynamic light scattering and rotating frame nuclear Overhauser effect spectroscopy.
