This paper is concerned with the preparation of organic and organometallic electrode surfaces by binding such species to the surfaces of conductors. A primary goal of this work is to attach redox reagents which will be pumped by the electrode and which will in turn react with specific solution species. The use of polymer adsorption as an alternative to covalently attachment is also described. In experiments, the authors have employed dip coating to produce layers 30-300 A thick (in vacuo). The modified electrodes are analyzed by ESCA Auger spectroscopy (AES) and used in solutions where the polymer does not desorb. Results are presented which show that adsorbed polymer layers of varying thickness can be reproducibly formed from various polymers. The use of these electrodes for electrochemical reactions on solution species revealed that the uncharged layer acts as an inhibitor while the charged layer conducts.
