1. Catenanes, rotaxanes and pseudorotaxanes are supramolecular systems suitably designed to perform mechanical movements upon photochemical, electrochemical, and chemical stimulations. 2. Suitably designed dendrimers and other multicomponent systems containing luminescent and/or electro-active moieties can perform the function of antennae for light harvesting or process light signals in a complex way. 3.  Suitably designed chemical systems are capable of performing logics operations (NOT, OR, AND, XOR) mimicking at molecular level the functions performed by logic gates. 

Her present reasearch activity is dedicated to the design, construction, and characterization of molecular-level devices and machines in the frame of the bottom-up approach to nanotechnology. An innovative aspect of this research is the idea that the concept of macroscopic device and machine can be extended to the molecular level, and that it is possible to design multicomponent systems capable of performing specific functions upon stimulation with external energy inputs. Up to now the studies in this research field succeeded in constructing (i) a number of systems for information processing such as wires, switches, antennas, batteries, logic gates, and (ii) a variety of systems that, powered by chemical energy, electrochemical energy, or light, exhibit machine-like behaviour such as piston-cylinder systems, shuttles, and rotary rings. Very recently a light powered nanomotor has been obtained which has been highlighted on several scientific journals. To investigate these systems a variety of techniques can be employed such as absorption and emission (steady-state and time resolved) spectroscopy, stopped-flow methods and electrochemical (cyclic voltammetry and spectroelectrochemistry) techniques.
