We introduce a facile new synthetic methodology for the preparation of alkyl pyridinium-containing acrylamide monomers. Inclusion complexes of these new monomers with CB facilitate supramolecular crosslinking in a series of hydrogel formed through in-situ polymerisation. The resulting hydrogels not only show greatly enhanced mechanical properties over a purely acrylamide- based gel but by selecting fluorescent pyridine moieties, the materials are endowed with the fluorescent properties desirable for several sensing applications.
