Aromatic carboxylic acid self-assembly has been a hot research field for many scientists due to its strong coordination ability and flexible coordination mode. 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.
