ABSTRACT
This work presents the synthesis of glucose-based vinyl imidazolium monomers and the hydrogels produced thereof. These novel semisynthetic, cationic hydrogels were prepared by radical polymerization with different types of commercial cross-linkers such as N,N'-methylenebis(acrylamide) or poly(ethylene glycol) diacrylate. Both the type and the amount of cross-linker were investigated as influencing factors with respect to the swelling degree. It was found that the cross-linker type majorly influences the swelling degree and long-term stability of the hydrogels. Last, the influence of different anions (e.g., halogens, acetate, and triflate) in the monomer molecule on the swelling properties of the hydrogels was investigated.
ABSTRACT
The title solvated molecular salt, [MeGluVIm]I (MeGluVIm = 1-(methyl-α-d-gluco-pyran-osid-6-yl)-3-vinyl-imidazolium), or C12H19N2O5 +·I-·C3H7NO, was synthesized from methyl-α-d-6-iodo-gluco-pyran-oside and vinyl-imidazole in DMF. It crystallizes through precipitation from ethyl acetate solution directly after the reaction procedure. The crystal structure consists of an iodide anion and a [MeGluVIm] cation. Furthermore, the crystal structure contains one mol-ecule of DMF, which accepts two O-Hâ¯H hydrogen bonds from the OH groups of the gluco-pyran-oside.
