Long-chain omegahydroxyalkanethiols [HS(CH(2))nOH] coordinate to gold surfaces through the sulfur atom and produce ordered, hydrophilic monolayers in which the hydroxyl groups are exposed at the outer surface. Coadsorption of two omega-hydroxyalkanethiols of different chain lengths n resulted in the formation of a monolayer having a disordered surface region that was markedly less hydrophilic than the homogeneous, hydroxylic surface formed from either pure compound. By controlling the composition of the monolayer, it was also possible to control simultaneously the degree of order in the surface and its hydrophilicity. In the monolayers containing a mixture of alkanethiol components, these components apparently did not phase-segregate into macroscopic islands, but were dispersed on a molecular scale. assistance and many useful discussions.
长链ω-羟烷硫醇[HS(CH(2))nOH]通过硫原子与金表面配位，并在金表面生成有序亲水的单层，其中羟基暴露在表面。两种不同链长 n 的ω-羟烷硫醇共吸附导致形成具有无序表面区域的单层，其亲水性明显低于由纯化合物形成的均相羟基表面。通过控制单层的组成，还可以同时控制表面的有序度及其亲水性。在含有混合烷硫醇组分的单层中，这些组分显然没有相分离成宏观岛，而是在分子尺度上分散。在此研究过程中得到了许多同行的帮助和有益的讨论。
