Resumen: Nowadays, electronic devices are a fundamental part of our daily lives and have transformed the world by implementing a huge variety of services, allowing communication and information sharing all over the world, and ultimately, improving our standard of living. All this has been possible by the development of technology, that is, scientific knowledge applied to the production of devices that can be mass-produced and purchased by anyone. However, due to the increasing miniaturization of these devices, current semiconductor technology is reaching its limit.
One of the alternatives to continue with the optimization and miniaturization of electronic devices is molecular electronics. This promising field uses organic compounds attached between electrodes as building blocks of the electronic devices. Single molecules or molecular assemblies can be sandwiched between the electrodes, each one oriented to a specific application. The advantage of using molecules is that they allow fabricating devices with different functionalities, which will depend on the intrinsic properties of the compound. In addition, collective effects that arise from the intermolecular interactions between molecules forming molecular assemblies are also important to take into account.
In this final master thesis, the possible use of two novel compounds in the field of molecular electronics is studied by the fabrication and characterization of monolayers. Both the Langmuir-Blodgett (LB) method and the self-assembly (SA) technique have been used to form the monolayer in terms to study the influence of the approach in the arrangement of the monolayer. However, due to the COVID19, the experimental work was interrupted, limiting the work to some preliminary results. Accordingly, a bibliographical review of the state of the art of molecular electronic devices has been carried out, to complement the work left uncomplete due to the global pandemic.
