Self-assembled molecular networks enable spatial and temporal control of surface chemical functionalities. However, in most cases, the deposition process is unsuitable to the growth of multilayers. In this study, we attempted the consecutive deposition of a two-dimensional supramolecular array on another to fabricate an organic layer (OL) and realize the growth mechanism on underlying inorganic layer of distinct ordered layers, each of which is stabilized by in-plane non-covalent bonds. An OL was formed by depositing pyromellitic acid (PMA) through ultrahigh-vacuum physical vapor deposition on a metal-oxide and metal-aluminate system tailored by plasma electrolytic oxidation, and the unique interface between the organic and inorganic layers was characterized by field-emission transmission electron microscopy under ambient conditions. The adsorption behavior of pyromellitic acid (PMA) on the inorganic surface was investigated by computational calculations. The adsorption of PMA over an inorganic surface was more favorable than the adsorption between PMA molecules themselves.

自组装分子网络能够控制表面化学功能的空间和时间。然而，在大多数情况下，沉积过程不适合多层的生长。在这项研究中，我们尝试在另一个二维超分子阵列上连续沉积以制造有机层（OL）并实现不同有序层的底层无机层的生长机制，每个层都通过面内非稳定层稳定-共价键。通过超高真空物理气相沉积在等离子体电解氧化定制的金属氧化物和金属铝酸盐体系上沉积均苯四酸 (PMA) 形成 OL，有机层和无机层之间的独特界面通过场发射表征环境条件下的透射电子显微镜。通过计算计算研究了均苯四酸（PMA）在无机表面上的吸附行为。PMA 在无机表面上的吸附比 PMA 分子本身之间的吸附更有利。
