采用和频法研究了自组装单层烷烃硫醇CnH2n / 1SH (n = 9,10,18)在Au, Ag(111)和Pt(111)上的电化学效应。Au和Ag(111)上的层没有明显的影响。Pt(111)上的层显示在负或正电位下可逆消除的间扭式变换。
Electrochemical effects on self-assembled monolayers of alkanethiols, CnH2n divided by 1SH (n = 9, 10, 18), on Au, Ag(111), and Pt(111) are investigated using sum-frequency generation. Layers on Au and Ag(111) show no noticeable effects. Layers on Pt(111) show gauche transformations that are reversibly eliminated at negative or positive potentials.
