Five copolymers were synthesized from vinylferrocene with N-(4-
methoxyphenyl)maleimide, N-(4-methylphenyl)maleimide, N-phenylmaleimide, N-
(4-acetylphenyl)maleimide, and N-(4-cyanophenyl)maleimide. The resulting
copolymers were characterized by gel permeation chromatography, IR spectroscopy
and NMR spectroscopy. Thermal characterization of the copolymers included DSC
and TGA. The copolymers were also characterized electrochemically by cyclic
voltammetry in methylene chloride solutions and as a thin film in aqueous
electrolytes. As a thin film, each copolymer showed changes in oxidation potential
with different electrolytes (NaCl, NaNO3, NaClO4, and Na2SO4). These materials
were also tested as biosensors for hydrogen peroxide and dopamine, and compared to
polyvinyl ferrocene. Each material exhibited similar sensitivity to hydrogen peroxide.
However, differences were observed when sensing dopamine with the methoxy and
nitrile derivatives being the most sensitive.
