Titanium dioxide is one of the most frequently studied metal oxides, and its (110) rutile surface serves as a prototypical model for the surface science of such materials. Recent studies have also shown that the (011) surface is relatively easy for preparation in ultra-high vacuum (UHV) and that both the (110) and (011) surfaces could be precisely characterized using scanning tunneling microscopy (STM). The supramolecular self-assembly of organic molecules on the surfaces of titanium dioxide plays an important role in nanofabrication, and it can control the formation and properties of nanostructures, leading to wide range of applications covering the fields of catalysis, coatings and fabrication of sensors and extends to the optoelectronic industry and medical usage. Although the majority of experiments and theoretical calculations are focused on the adsorption of relatively small organic species, in recent years, there has been increasing interest in the properties of larger molecules that have several aromatic rings in which functional units could also be observed. The purpose of this review is to summarize the achievements in the study of single polycyclic molecules and thin layers adsorbed onto the surfaces of single crystalline titanium dioxide over the past decade.
二氧化钛是研究最多的金属氧化物之一，其（110）金红石表面是此类材料表面科学的典型模型。最近的研究还表明，（011）表面在超高真空（UHV）中相对容易制备，并且（110）和（011）表面都可以使用扫描隧道显微镜（STM）进行精确表征。在二氧化钛表面上的有机分子的超分子自组装在纳米制造中起着重要作用，它可以控制纳米结构的形成和性质，从而在催化、涂层和传感器制造等领域得到广泛应用，并扩展到光电行业和医疗用途。尽管大多数实验和理论计算都集中在相对较小的有机物种的吸附上，但近年来，人们对具有多个芳环的较大分子的性质越来越感兴趣，其中也可以观察到功能单元。本文综述了过去十年中在单晶二氧化钛表面上吸附的单环多环分子和薄膜的研究进展。
