| Summary: | The reduction of electrodes coated with C60-fullerene is examined in acetonitrile solution containing a wide variety of supporting electrolytes (MClO4; M = Li, Na, Ba0.5, NR4). Electrochemical intercalation is observed with the formation of fulleride salts. Intercalation is typically irreversible except for the case of R = n-butyl where stable coats of fullerides may be formed into which charge can be passed with near chemical reversibility. Electron-transfer reactions at electrodes modified with C60 coatings were investigated for diverse substrates. With unreduced coats impeded diffusion to the metal surface was seen, whereas with films reduced in the presence of tetrabutylammonium perchlorate coat-mediated electron transfer to the substrate was possible. © 1993. |
