Abstract:
The synthesis of a rapidly forming redox responsive poly(ferrocenylsilane)-poly(ethylene glycol) (PFS-PEG)-based hydrogel is described, achieved by a thiol-Michael addition click reaction. PFS bearing acrylate side groups (PFS-acryl) was synthesized by side group modification of poly(ferrocenyl(3-iodopropyl)methylsilane) (PFS-I) and characterized by (1) H NMR, (13) C NMR, and FT-IR spectroscopy. The equilibrium swelling ratio, morphology, rheology, and redox responsive properties of the PFS-PEG-based hydrogel are reported.
