Final Activity Report Summary - SUPER (Supramolecular devices at surfaces)
SUPER provided highest level of training through research to five most promising young early stage researchers in four main areas of research: 1. supramolecular synthetic chemistry, development of complex arrangements with potential for construction of prototypes of nanowires and switches; 2. nanofabrication of metallic nanostructures using top-down approaches; 3. study of the self-assembly of hybrid metallic-supramolecular architectures and tuning the properties of a single molecule in a supramolecular ensemble at surfaces; 4. development of prototypes of supramolecular wires and switches operating at surfaces. The project overall made it possible for these young researchers to acquire an interdisciplinary education by investigating in detail the relationship between architecture and function in supramolecular systems for organic- and nano-electronics. In particular, the use of nanoscale approaches allowed for the study of various physicochemical properties of supramolecular architectures. Such findings were crucial for the optimisation of nanodevices' performance. The appointees were exposed to training in this emerging field at the interface between chemistry, physics and engineering. The training combined indoors and outdoors activity. The indoors included the active laboratory research under the supervision of the PhD thesis advisor, following courses at the doctoral school, participation to over 50 conferences, seminars and workshops organised at ISIS-ULP in the frame of SUPER, as well as the active participation to weekly group meetings. Outdoors included active participation to international conferences and schools as well as short visits to other laboratories of external collaborators. The success of the project was reflected, among others, by the long list of publications in high ranking journals as well as by presentations at conferences.

Project objective
SUPER will offer a multidisciplinary training to young researchers in the art of nanoscience and nanotechnology, in particular on the building-up of key units for the future organic nanoelectronics. Research will include synthesis, analysis, self-assembly of supramolecular (SM) architectures at surfaces, their Characterisation across a wide range of length and time scales and their use in the fabrication of wires, switches and motors operating at surfaces. Scanning Probe Microscopies (SPMs) will grant study of the nanoscale physico-chemical properties of self-assembled complex arrangements and the manipulation of single molecules embedded in a SM ensemble. Observing how the induced mechano-chemical transition is reflected on the neighbouring molecules, one can tune the properties of the SM architecture at surfaces, paving the way towards prototypes of nanowires. Nanofabrication of metallic nanoelectrodes and SM synthesis provide tools for the implementation of nanowires.Systematic studies on the optimisation of the conductivity of SM anisotropic objects will be done varying the wire: chemical composition; conformation; length; doping. This will offer protocols for the fabrication of SM nanowires. SM switches operating at surfaces will be developed, where the motion will be triggered by different stimuli, i.e. light, variation of pH, an applied redox potential. Rod-like molecules capable of switching between coiled to rigid conformations will permit to bridge and unbridge the gap between two nanoelectrodes, controlling the on-off switching. Prototypes of molecular motors based on rotaxanes, where the switching is accompanied by an action, i.e. a delivery of a small moiety, will be fabricated. This research on the fabrication of key units for future nanoelectronics, will be vital for implementing organic based integrated circuits and for the optimisation of macroscopic devices, such as Light Emitting Diodes, Solar Cells and Field Effect Transistors.
