- 中文摘要: Electropolymerization of pyrrole in aqueous solution is monitored by electrochemical quartz crystal microbalance (EQCM) during potential scan. The film formation process on the electrode is reflected by the frequency decrease for the quartz oscillator as a function of time. The film growth rate is greatly enhanced in the presence of iron(III) meso-tetrakis (3-sulfonatomesityl)porphyrin, which carries 3- of charge. The metalloporphyrin is trapped and remains intact in the polypyrrole films. The ion transport property through the iron porphyrin/polypyrrole film is the reverse of that for pure polypyrrole. Electroreduction of dioxygen and electrooxidation of alkenes are parallel to those in the solution state.
