Abstract: This Thesis concerns the study of the switchable behavior on surface of specifically designed electroactive molecules by fabricating self-assembled monolayers (SAMs).
Subsequently to the study on surface, the molecules were integrated into various devices in order to investigate the effects of the electroactive switch in sophisticated systems.
Four family of electroactive molecules were employed, namely antraquinones (AQ), ferrocenes (Fc), tetrathiafulvalenes (TTF) and polyclorotriphenylmethy (PTM) derivatives.The investigation of the switching properties on surface was carried out by using as read-out mechanism the optical, magnetic, the capacitance response and the host-guest interactions with β-cyclodextrins.
Systems with multiple accessible states and with confined properties were realized.Furthermore, SAMs of AQ on ITO were used to realize water actuators, while SAMs of Fc, TTF and PTM derivatives were integrated in Field Effect Transistors, opening new perspectives for the molecule-based technologies.
