Polyethyleneimine (PEI) microgels were synthesized and characterization according to the literature. Here, we report the Ferrocene modification of PEI microgels (Ferrocene-PEI) from the reaction of Ferrocenecarboxaldehyde with PEI microgels, and the scheme of the modification reaction is given in (Scheme 1).<br/><br/>The Ferrocene-PEI microgels were characterized via FT-IR, SEM, TG analysis, and the degree of modification of PEI microgels with Ferrocene was determined from the amounts of Fe ions via Atomic Absorption Spectroscopy (AAS). The Ferrocene-PEI microgels show diamagnetic moment predicted by magnetic susceptibility measurements with the Gouy method, and confirmed by FT-IR of modified microgel.
