LB and LS are used to make well-controlled surfaces. This technology can be applied to the creation molecular level electronic devices by using supramolecular assembly at interfaces.
LB and LS can be used in fabrication of well-controlled surfaces. This can be used to create molecular level electronic devices by supramolecular assembly at interfaces. It is also possible to prepare single-molecule thin electronic devices from, for example, graphene, carbon nanotubes and nano- or micro-sized metal particles or rods.

Conjugated photoactive perylendiimide dyes could be fabricated into optoelectronic devices by sequential LS dipping of the dye molecules from air-water interface. The molecules formed columnar aggregates perpendicular to the surface which displayed charge transfer properties that are did not occur in randomly-oriented film of the same molecule prepared by spin coating.
