Abstract
Novel poly(ferrocenyl n butylmethylsilane) with unsymmetrical silicon substitution groups [Fe(η-C 5H 4) 2(SiBuMe)] n (PFBMS) ( 6) have been prepared via the thermal ring-opening polymerization (ROP) of the corresponding strained silicon-bridge [1] ferrocenophanes [Fe(η-C 5H 4) 2(SiBuMe)] ( 4) and via the nucleophilic substitution of poly(ferrocenylmethylchlorosilane) [Fe(η-C 5H 4) 2(SiMeCl)] n ( 5) with n-butyllithium. Resultant PFBMS was structurally characterized by 1H NMR and UV/visible spectroscopy. The molecular weights of PFBMS ( 6) were measured by gel permeation chromatography (GPC) using polystyrene standard, and the solution electrochemical behavior of PFBMS was investigated by cyclic voltammetry (CV).
