这项研究表明，通过从稀溶液中吸附，可以在氧化的铝衬底上形成最紧密堆积的、定向的正构烷酸单分子膜。这些有机表面相的形成具有复杂的动力学特征，表面和/或单层缺陷以及杂质似乎在其中起着重要作用。这样得到的结构本质上是动态的，因为它们在溶液中与配体进行快速交换。这些数据进一步表明了该体系中自组装的一个重要限制，这与正构烷酸尾的长度直接相关。讨论了实验参数对取向单分子膜形成的影响。
This study shows that closest packed, oriented monolayers of n-alkanoic acids can be formed on oxidized aluminum substrates by adsorption from dilute solution. The formation of these organic surface phases is characterizedby complicated kinetics in which surface and/or monolayer defects, as well as impurities, seemingly play important roles. The structures so obtained are dynamic in nature inthat theyundergo rapid exchange with ligands in solution. The data further suggest an important limitation to self-assembly in this system which is directly related to the length of the n-alkanoic acid tail. The influences of experimental variables on the formationof orientedmonolayers is discussed.
