Abstract

The Langmuir-Blodgett-technique is a method to build up thin organic films with well-defined thickness and structure, which have many possible applications e.g. in molecular electronics for signal processing and transport. Monolayer film formation has been observed for different donor-acceptor substituted polyenes and was characterized on the water surface by pressure-area isotherms. The films were successfully transferred onto several substrates like glass, silicon and silver coated glass substrates by vertical dipping. The transferred LB mono and multilayers were characterized by IR spectroscopy and surface plasmon resonance (SPR), which is a promising technique for the investigation of thickness and index of refraction of the organic layers. Monolayer films of polyenes with long aliphatic chains were investigated by Scanning Tunnelling Microscopy (STM). Images with two different periodicities indicative of the aliphatic chains and of the conjugated system, respectively, have been observed.
