在Au（111）表面，由3-巯基-1-丙醇和1-十四烷醇（TDT）组成的二元自组装膜（SAMs）的相分离区域的结构强烈依赖于形成SAMs的溶液的硫醇浓度。循环伏安曲线和扫描隧道显微镜图像表明，1×10− 6 moldm − 3硫醇溶液形成的二元SAM表现出特征性的指状畴相分离，长而窄的富TDT畴向Au衬底的方向延伸.随着用于制备SAM的硫醇溶液的浓度降低，域的尺寸变得更长，相分离的程度变得更高。
The structure of the domains of phase-separated binary self-assembled monolayers (SAMs) composed of 3-mercapto-1-propanol and 1-tetradecanethiol (TDT) on Au(111) strongly depends on the thiol concentration of the solution from which the SAM is formed. Cyclic voltammograms and scanning tunneling microscopic images show that a binary SAM formed from 1×10−6mol dm−3concentration of a thiol solution exhibits the phase separation with characteristic finger-shaped domains, long and narrow TDT-rich domains elongate to 〈1 0 1〉 directions of the Au substrate. The size of the domains becomes longer and the degree of phase-separation becomes higher as the concentration of the thiol solution used in preparing the SAM is lower.
