Abstract: This thesis is focused on the development of new molecular electronic devices based on electroactive self-assembled monolayers (SAMs), and on the electrochemical study of the electron transfer (ET) phenomena associated to them. In the first part, it is described the use of different redox molecules immobilized on gold as molecular switches. In the second part, it is reported the ET mechanism study, by electrochemical means, in a family of polychlorothriphenylmethyl radical (PTM) derivative compounds attached to gold. It has been studied the ET process in different organic electrolytic media and as a function of the surface coverage of the modified gold. Finally, it has been also fabricated a functioning OFET using an ion gel as gate dielectric, demonstrating that the ion gels are highly attractive to be applied in low cost and flexible organic transistors.
