• (undecan-1-ol or decan-1-ol), coadsorbed out of a solution of the acid within the alcohol at the interface of highly oriented pyrolytic graphite (HOPG) (0001) substrate. The monoester was observed promptly after reaching a threshold either related to the increased packing density of the adsorbate layer

• . Here we present a chemical reaction (esterification) between trimesic acid (benzene-1,3,5-tricarboxylic acid; TMA) dissolved in an alcoholic solvent (undecan-1-ol or decan-1-ol) on a highly oriented pyrolytic graphite (HOPG) (0001) substrate. The reaction proceeds without catalyst and is controlled by
