中文摘要	Single-component monolayer of novel multi-thiol coronary molecule and two-component mixedmonolayer composed of coronary molecule and n-alkanethiol on gold substrates are described. Theassembly ofmonolayers is characterized by ellipsometry, infrared spectroscopy and X-ray photoelectronspectroscope. The electrochemical properties of the single- and two-component monolayers areevaluated by cyclic voltammetry and electrochemical impedance spectroscopy experiments. Coronarymolecule with multi-thiol groups has the ability to form stable monolayer via the interaction omercapto groups and Au surface. Electrochemical impedance measurements indicate that 89.9% of thegold surface is blocked by the coronary molecule, which is attributed to the special spatial structure othe coronary molecule. The uncovered site on gold surface in coronary molecule monolayer could beoccupied by the second suitable molecule. The mixed monolayer prepared by stepwise assembly ocoronary molecule and n-alkanethiol has complete compact packing and few defects.
