The hydrogen bond formed between aromatic carboxylic acids is a strong intermolecular force and has directionality and saturation, which plays a very important role in the self-assembly and regulation of aromatic carboxylic acids. In this review, we introduce surface organization formed by aromatic carboxylic acids with the aid of scanning tunneling microscopy (STM). These two-dimensional structures include molecular templates, host-guest systems, and photo-isomerization structures. We also emphasize the thermodynamics and dynamics, which are important research topics of current and future study.Graphical AbstractIn this review, varieties of aromatic carboxylic acids are introduced to self-assemble into molecular templates, host-guest systems, and photo-isomerization structures.
