AbstractAdsorption of pyridine, pyrazine, and triazine molecules on a Cu(111) electrode surface was studied in aqueous solution by using cyclic voltammetry and electrochemical scanning tunneling microscopy (STM). High-resolution STM imaging reveals the details of the adlayer structures and internal structure of individual molecules. The molecules are found to form long-range well-ordered adlayers. The same (3 x 3) structures with a coverage of 0.11 are observed on the three adlayers. All three molecules adopt flat-lying orientation in the double-layer potential region, although the adsorption geometries are different. pi electrons are believed to be important in stabilizing the molecules in flat-lying orientation. Three structural models are proposed for the three adlayers.
