A better defined crystalline flat electrode usually provides a structurally more ordered organic monolayer, although the use of a single-crystalline electrode costs more for mass production. Because the monolayer structures at both molecular and mesoscopic levels are critical to the functions of the modified electrode, in-depth experimental studies to clarify the relationship between the functions and the surface morphology of the electrode are crucial. In this work, we compared polycrystalline Au (poly-Au) and single-crystalline Au(1 1 1) electrodes as the substrates for a redox-active, self-assembled monolayer (SAM) of an alkyl-viologen thiol, 1-(10-mercaptodecyl)-1′-methyl-4,4′-bipyridinium dibromide (MeVC10-SH 2Br−). The voltammetric and electroreflectance measurements were performed at a mirror-polished poly-Au electrode and a flame-annealed single-crystalline Au(1 1 1) electrode after their surface modification with a MeVC10-SH monolayer. We found significant differences in the anion effects on the voltammetric behavior between the two substrates, especially in the dependence on anion hydrophobicity. The electroreflectance spectra revealed a tendency that a greater abundance of the viologen radical cation dimers at a Au(1 1 1) than that at a poly-Au. A considerable Br− adsorption at the SAM-modified Au(1 1 1) electrode was observed because of the loose packing of immobilized MeVC10-SH molecules. We discussed the origins of the contrasting behavior resulting from the difference of the surface.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Journal of Electroanalytical Chemistry, 919, art. no. 116514; 2022　","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier B.V."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jelechem.2022.116514","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2022 Elsevier B.V.
