Structure and Electronic Properties of Self-Assembled Macrocycle and PolymerMultilayers

摘要

Layer-by-layer (LBL) self-assembly technique has been widely used to fabricateartificial thin films for a number of potential applications with several advantages. First, many materials with charges can be chosen as building blocks for this simple approach to thin-film fabrication; this includes conducting polymers, optical chromophores, metal complexes, or semiconductor nanoparticles. Second, LBL self-assembly processes are much simpler when compared to the Langmuir-Blodgett technique, or chemical/physical vapor depositions. Finally, by controlling length scale at the nanometer level, LBL approach can be used to construct materials with designed properties for applications in electronics, photonics, and optoelectronics. Since the interfaces between each layer become the key linkages for multilayers and therefore interface properties are crucial to the self-assembled systems.
