Adlayer structures of benzene and pyridine molecules on Cu(100) in solution by ECSTM
Adsorption of benzene (C6H6) and pyridine (C5H5N) on Cu(100) has been investigated in eletrolyte solution by using cyclic voltammetry and in situ scanning tunneling microscopy (STM). Both molecules adsorbed on Cu(100) surface in HClO4 solution and formed well-defined (2 x 2) structures with a flat-lying orientation. Structural models were proposed to interpret the bonding and coordination of the two molecules with Cu(100) surface.
