Abstract
A novel star-[polystyrene-b-poly(ferrocenyloxy ethyl acryl ate)]6 with hexa- functional cyclotriphosphazene core (star-(PS-b-PFcEA)6) was synthesized by atom -transfer radical polymerization(ATRP) and its electrochemical behaviors and anion recognition was investigated through CV. The results indicated that increasing of molecular weight resulted in obvious decreasing of reduction peak potential Epc, and the oxidation peak potential Epa kept comparatively stable. Moreover, when titrating anion into polymer solution, Epc increased while Epa reduced evidently, which suggested that star-(PS-b-PFcEA)6 provided with high anion recognition capacity of
