A summary is given of the outline of the preparation technique of Langmuir-Blodgett (LB) films as a tool to construct man-made molecular assemblies which are of potential use in molecular electronics. The conductive Langmuir-Blodgett films are briefly reviewed as representing the recent endeavors of developing novel functional materials in the form of ultrathin films. The analytical model of flow orientation is touched upon as an example of the quantitative approach to the dynamic aspects of the LB preparation technique.
