Langmuir-Blodgett films molecular design

Besides self-assembly on the surface of metals, another example of self-assembly is the formation of Langmuir-Blodgett monolayers on the surface or at the interface of liquids.47,48 One approach to molecular-based electronic devices that has made use of self-assembled Langmuir-Blodgett films is the crossbar-based defect-tolerant approach to molecular computing 49 Rotaxane molecules that depend on physical dislocations within the molecule to produce switching functionality have been designed such that they will... 

The organic thin films used in lithography are polymer casting films, Langmuir-Blodgett (LB) films, SAMs and plasma-polymerized films. The molecular designs and syntheses of organic monolayer materials are studied for SPNL resists [89]. 

By its very nature, copolymerization offers the unique capability or opportunity for chemists to design and construct molecules with special electronic properties using established techniques. The Langmuir-Blodgett (LB) technique, for instance, enables the chemist to organize molecules into highly ordered monolayers and to manipulate a multilayer film to a desired architecture. Copolymerization enables the molecular architect or tailor to incorporate various molecules, e.g. biological components, into electroactive PP and PT polymers. The number of potential applications for these unique materials is unlimited. 

The focus in the thin film research impact area is to develop a fundamental understanding of how morphology can be controlled in (1) organic thin film composites prepared by Langmuir Blodgett (LB) monolayer and multilayer techniques and (2) the molecular design of membrane systems using ionomers and selected supported liquids. Controlled structures of this nature will find immediate apphcation in several aspects of smart materials development, particularly in microsensors.
