The nanoscale assembly strategies based on the Langmuir–Blodgett (LB) technique were highlighted to demonstrate the potential for functional device fabrication. (1) The assembly of silsesquioxane-containing polymers can be used to produce uniform monolayers, which are precursors of ultrathin SiO2 films with controlled porosity. (2) The assembly of inorganic nanoparticles and metal-organic framework films on polymer films demonstrates the importance of the spatial alignment of anchoring units. (3) The assembly of π-conjugated units can be used for high-density and low-dimensional assembly.
