Due to their unique physical characteristics, surfactants containing fluorocarbon chains form hierarchical patterns of two-dimensional mesoscopic/microscopic self-assemblies on the surface of water. This review describes the overarching physical mechanism, the competitive interplay of line tension and dipole interaction and discusses several key experimental and analytical techniques characterizing the shape, size, correlation, and viscoelasticity of mesoscopic/microscopic self-assemblies on water, which is often non-trivial. Some of the recent biomedical applications, including biomimetic surface coating, contrast agents in multimodal imaging, and controlled delivery, are introduced to highlight how the unique physicochemical properties of fluorinated self-assemblies can be applied in materials science.
