内容記述 | Phase transition behavior of two-component viologen adsorption layers at a HOPG electrode was described using the results of voltammetric measurements. In the coexistence of heptyl viologen (HV) and its bis-carboxylated derivative in the solution phase, a well-mixed condensed monolayer of the radical cations was formed at any molar fraction. In sharp contrast, the binary system of HV and butyl viologen (BV) exhibited phase separation in the molar fraction range where BV is saturated in the predominantly formed condensed phase of HV. It was, however, found that this separation, being opposed to the prediction based on the adsorption free energy, occurs only when the time period enough for full condensation of HV is not given. The significant features of phase transition of two-component viologen adsorption layers on a HOPG electrode surface were highlighted in comparison with the formation and reductive desorption of the self-assembled monolayers of alkanethiols. | |||||
