Dynamics of nm to μm size ordered structure formation of adsorbed monolayers at solid surfaces and spread monolayers on water surface studied by probe microscope is reviewed. The most important requirement for forming ordered molecular films on the solid surfaces is the constrained movement of the adsorbed molecules at the solid surface potentials. Two-dimensional cluster formation of nm size is a rather general phenomenon of the spread monolayers of the materials forming condensed films. However, they generally fuse into large domains spontaneously for simple amphiphiles such as long-chain acids. Partially fluorinated long-chain acids form very stable monodisperse nm size clusters in the spread monolayers by the mismatch of cross sections of hydrocarbon and fluorocarbon parts. Some other examples of forming such structures are shown.
