A target of this review is soft 2D nanoarchitectonics because scientific views on soft 2D nanomaterials are not fully established as compared with rigid 2D materials. The presented examples are selected according to the following three categories on the basis of 2D spatial density and motional freedoms: (i) well-packed and oriented organic 2D materials with rational design of component molecules and device applications, (ii) well-defined assemblies with 2D porous structures as 2D network materials, and (iii) 2D controls of molecular machines and receptors on the basis of certain motional freedom with confined nature in 2D plain.
