      abstract     = {The adsorption and phase formation of 3 mmol L-1 trimesic
                      acid (TMA) on Au(111-25 nm) film electrodes in contact with
                      aq. 0.1 mol L-1 HClO4 electrolyte have been investigated by
                      in situ ATR-SEIRAS, cyclic voltammetry, chronoamperometry,
                      and STM measurements. Depending on the applied electrode
                      potential, TMA molecules assemble in three distinctly
                      different 2D ordered adlayers. In the range 0.10 < E < 0.50
                      V, planar-oriented molecules form an open ring honeycomb
                      pattern (phase I) stabilized by directional hydrogen bonds.
                      Interfacial water molecules are being replaced. A
                      close-packed, physisorbed adlayer II forms at higher
                      potentials in the range 0.58 < E < 0.75 V. Further increase
                      of the electrode potential causes an orientation change. An
                      initially disordered phase transforms into an ordered,
                      stripe-like chemisorbed adlayer III of perpendicularly
                      oriented TMA molecules (0.90 < E < 1.20 V). One carboxylate
                      group per molecule is bound to the electrode surface, while
                      the two other protonated carboxyl groups are directed toward
                      the electrolyte, and act as structure-determining components
                      of a hydrogen-bonded molecular ladder network. Strongly
                      hydrogen-bonded and isolated water species are co-adsorbed.
                      The potential-induced formation of chemisorbed TMA proceeds
                      in two steps: (i) orientation change from planar to a
                      disordered tilted and (or) perpendicular phase IIIa (tau < 5
                      ms) according to a Langmuir-type kinetics; (ii)
                      subsequently, the chemisorbed TMA molecules align into a
                      highly ordered, stripe-like phase IIIb with co-adsorbed
                      water species.},
