Surface chemistry of five-membered heteroaromatics at Pt(III) electrodes studied by EELS, LEED, Auger spectroscopy and electrochemistry: furan, pyrrole and thiophene

Self-assembly of mono- and multilayers of polyconjugated conducting polymers

“…This value is high, ca. twice as reported 78) for a ferrocene monolayer (4.5 N 10 -10 mol N cm -2 ), which points to a high packing of the polymer chains. On the contrary in the case of the sexithiophene 26 the coverage is comparable with that of ferrocene.…”

Spectroscopic and electrochemical characterization of interfacial biomimetic assemblies on electrochemically generated gold oxide surfaces

“…The insert shows the voltammetric peak current dependence of the scan rate, which is linear over the potential scan rate range studied here, indicating that the redox couple is surface-bound. Integration of the surface charge (the electrochemical area of electrode was used, which is likely more appropriate than geometric estimations based on the sphere radius [37,40,43]) of ferrocene oxidation (or reduction of the ferrocenium species yields a surface coverage of 1.5Â10 À10 mol cm À2 , somewhat lower than that expected for monolayer coverage (4Â10 À10 mol cm À2 ) [38][39][40][41] and ca. five times smaller than the density reported for an alkanethiol monolayer (7.7Â10 À10 mol cm À2 ) [42].…”

Modification of Transparent Conducting Oxide ( TCO ) Electrodes through Silanization and Chemisorption of Small Molecules

“…1 × 10 −10 mols cm −2 ) occurring at approximately 10 mM solution concentration. The saturation coverage, however, was 25% of the expected monolayer coverage (4 × 10 −10 mols cm −2 ) based on the geometric area [65]. Fc(COOH) 2 was adsorbed from ethanol, while Fc[(CH 2 ) 6 COOH] was adsorbed from hexane.…”
