摘要

Reactive, deoxygenated glassy carbon surfaces prepared by mechanical abrasion under nitrogen or argon plasma etching react with selected molecules to yield surfaces with immobilized molecular surface states. Vinyl ferrocene and a ruthenium pyridine complex are immobilized on glassy carbon in this way. Introduction of vinyl ferrocene directly into an RF plasma discharge leads to electroactive ferrocene polymer deposition on glassy carbon and Pt surfaces. Surface waves corresponding to 3 x ten to the minus 8th power moles/sq cm ferrocene are obtained in this way. (Author)
