Langmuir-Blodget

Because of some apparent restrictions, organic materials including polymers are not very suitable for electrical SPL. First, the surface structure of organic materials is less stable and less defined compared to inorganic solids. Second, the materials to be used for electrical SPL have to be either electrically or optically active. Most of the SPL experiments have used Langmuir-Blodget films and self-assembled monolayers (SAM s) due to their well defined thickness, orientation of the molecules and uniform surface composition [446-450]. [Pg.137]

Although several methods may be used to fabricate the organic layers in OLEDs, such as thermal evaporation, Langmuir-Blodget deposition or spin coating from solutions, RE + /3-diketonates usually are deposited by thermal evaporation techniques, under high vacuum ca 10 Pa) thus, volatility and thermal stability of the diketonates are required. ... [Pg.161]

A new area of polymer science termed nano-macromolecular chemistry [Eirich, 1993] also has relevance to future polymer blend technology and application. Langmuir-Blodget techniques allow for the formation of films of one molecule thickness. Utilizing polymerizable molecules for these films, a polymer molecule or network can yield a film with the thickness of several nanometers. Alternating layers comprised of different polymers could be prepared to yield specific optical or electrical properties. Polymerization of calix-arenes to yield molecular sieving membranes for gas separation has been discussed by Conner et al. [1993]. [Pg.1192]
