Synthesis and characterization of supramolecular cross-linkers containing cyclodextrin dimer and trimer†
Abstract
Vinylic supramolecular cross-linkers (VSCs) were prepared by mixing an α-cyclodextrin dimer or a trimer and a polyethylene glycol-type macromonomer. DOSY NMR study exhibited the size of VSC and its dependency on the concentration and the structure of the components. Polymerization of a vinyl monomer with VSC afforded rotaxane cross-linked polymers.
