SUPramolEculaR functional nanoscale archItectures for Organic electronics: a host-driven network

Final Report Summary - SUPERIOR (SUPramolEculaR functional nanoscale archItectures for Organic electronics: a host-driven network)

The SUPERIOR Network was a Marie Curie Initial Training Network (ITN) funded by the European Community's Seventh Framework Programme FP7-PEOPLE-ITN-2008. The 4-year training and research network started the 1st of October of 2009 and finished on the 30th of September 2013.

SUPERIOR aimed to provide top-quality cross-disciplinary and supra-sectoral training to a pool of promising young researchers, in an area at the interface between Supramolecular Chemistry, Materials- and Nano-Science, Physics and Electrical Engineering. SUPERIOR was designed to generate new scientific and technological knowledge by combining supramolecularly-engineered nanostructured materials (SENMs), mostly based on organic semiconductors, with tailor-made interfaces to solid substrates and electrodes, for fabricating prototypes of optoelectronic devices. Thus SUPERIOR’s impact is long-term and offered cutting-edge research opportunities to a range of young scientists from throughout Europe and further afield. We were particularly interested in developing multiscale SENMs for transistors (FETs), in-plane diodes single-photon emitters, and especially solar cells (PVDs) and organic light-emitting diodes, OLEDs.

The specific training and research objectives were:

1. Supramolecular synthetic chemistry of electrically/optically 1D and 2D (macro)molecules.
2. Hierarchical self-organisation of multifunctional SENMs at surfaces. Multiscale SPMs studies of physico-chemical properties.
3. Time-resolved photophysical studies of single-molecules and SENMs.
4. Time-resolved spectroscopy of materials and devices.
5. Modelling the geometric and electronic structures and the optical properties of SENMs.
6. Advanced devices processing/(nano)fabrication.
7. Formation of controlled interfaces of SENMs with substrate and electrodes.
8. Devices I: FETs – Measurement of charge mobility in stacks, also upon photodoping.
9. Devices II: PVDs – Addressing the charge collection problem.
10. Devices III: Emissive devices – Single photon emitters and OLEDs.

The network consisted of 7 interdisciplinary academic groups (University of Strasbourg, University of Cambridge, Katholieke Universiteit Leuven, Max-Planck Institute for Polymer Research, University College London, University of Mons, University of Nijmegen) and 2 industrial partners (BASF, APE Research) from 6 different countries.

Throughout the project, the appointees involved in SUPERIOR showed very effective integration, as illustrated by numerous transfers of materials and collaborations, common publications, bilateral meetings, research secondments (a total of 30) and conferences attended. The training received by the appointees spans from the modelling and synthesis of functional SENMS, to the characterisation and mapping of their opto-electronic properties and the introduction of the systems into devices. A total of 89 articles have been published in high impact scientific journals: 16 during the first year, 32 in the second year, 23 in the third year, and 18 in the final year. All of the milestones and tasks were reached in due time. The progress achieved in all Work Packages was in line with the initial plan and is summarized in the following section.
