Current silicon-based technology presents significant drawbacks from a technological and economical point of view. Therefore, molecular electronics is presented as a supporting tool; based on the use of organic or organometallic molecules as basic elements nanoelectronics. This Final Master Thesis aims at the formation of monolayers of a suitably functionalized organic compound, trough the transference of monolayers formed at the air water interface onto solid substrates and how the pH of the subphase can influence on the formation of them, as well as for the study of the surface behaviour of it.The formation of the monolayers has been carried out using the Langmuir-Blodgett technique and subsequently the films have been characterized both at the air-water interface (Langmuir films) and on the surface of a substrate (Langmuir-Blodgett films) by using a set of techniques such as surface pressure isotherms versus area per molecule, surface potential isotherms versus area per molecule, Brewster angle microscopy (BAM), UV-Vis reflection spectroscopy, atomic force microscopy (AFM), UV-vis absorption spectroscopy, cyclic voltammetry (CV) or quartz crystal microbalance (QCM).<br /
