title: Glucosamine hydrochloride functionalized water-soluble conjugated polyfluorene: synthesis, characterization, and interactions with DNA.
abstract: Novel glucosamine hydrochloride functionalized water-soluble conjugated polyfluorene was easily synthesized through Cu(I)-catalyzed azide/alkyne "click" ligation and Suzuki coupling polymerization. The water-solubility and biocompatibility of the polymer were improved after grafting glucosamine hydrochloride to the side chains of the conjugated polymer. As a fluorescent model system of chitosan, its interaction with single-stranded DNA was studied by spectrofluorometric titration.
