Abstract

The oxidation of xanthine adsorbed at the water-graphite interface has been studied in real-time with scanning tunneling microscopy (STM) and atomic force microscopy (AFM). The reaction was found to start preferentially from defect sites. The molecular packing structures of both the reactant and the product molecules were determined from the molecular resolution AFM images. Superperiodic structures of both the reactant and the product were observed in the STM images which were attributed to the electronic modulations of the underlying lattice on the molecular monolayers.
