Synthesis of ferrocene boronic acid-based block copolymers via RAFT polymerization and their micellization, redox responsive and glucose sensing properties

Publication date: Available online 26 May 2017 Source:Arabian Journal of Chemistry Author(s): Muhammad Saleem, Li Wang, Haojie Yu, Zain-ul- Abdin Current study is focused on the synthesis of three novel diblock copolymers poly(2-(methacrylolyoxy)ethyl ferrocene carboxylate-b-polymethyl vinyl amido phenyl boronic acid, poly(2-(methacrylolyoxy) ethyl ferrocene carboxylate-b-poly vinylamido phenyl boronic acid and poly(2-(methacrylolyoxy)ethyl ferrocene carboxylate-b-polystyrene boronic acid by using S-methoxycarbonylphenylmethyl dithiobenzoate as reversible addition–fragmentation chain transfer polymerization agent. The synthesized block copolymers were characterized by gel permeation chromatography, fourier transform infrared spectroscopy, 1H nuclear magnetic resonance spectroscopy, dynamic light scattering, scanning electron microscopy and transmission electron microscopy. Detailed micellization behaviour of poly (2-(methacrylolyoxy)ethyl ferrocene carboxylate-b-polymethyl vinyl amido phenyl boronic acid (in binary organic solvents mixture and aqueous solution) was studied. Comparative studies of micellization showed that the larger aggregates were obtained in binary organic solvents system than during dialysis in aqueous medium. The redox responsive behaviour of poly (2-(methacrylolyoxy)ethyl ferrocene carboxylate-b-polymethyl vinyl amido phenyl boronic acid was investigated by water soluble oxidizing (Ammonium cerium nitrate) and reducing (Sodium hydrogen sulphite) ...
