The overall goal of SUPRAMATES is to generate new 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. We are particularly interested in developing multiscale SENMs for transistors, in-plane diodes single-photon emitters (useful for quantum cryptography), and especially photovoltaic cells and OLEDs.
The primary objectives of SUPRAMATES are:
- Supramolecular synthetic chemistry: bottom-up fabrication of electrically and optically active functionalized
carbon-based 1D, 2D, 3D nano-objects and multichromophoric polymeric architectures - Hierarchical self-organisation of multifunctional SENMs at surfaces. SPMs studies of physico-chemical
properties of SENMs across different lengthscales - Time-resolved photophysical studies of single-molecules and SENMs
- Time-resolved spectroscopy of materials and devices: fundamental photophysics of SENMs to investigate charge injection/transport, charge generation via exciton splitting at different heterojunctions (fs-to-ms timescales)
- Advanced devices processing: Top-down (nano)fabrication by E-beam/FIB, and SPM-nanolithography
Bottom-up (nano)fabrication of controlled electrodes: Fabrication of FETs structures with sub-100 nm channels - Formation of controlled interfaces of SENMs at surfaces with both substrate and electrodes, also using zone-casting deposition of SENMs
- Devices I: Transistors: a) Measurement of charge mobility in stacks by transistors characteristics characterisation. b) transistors characterisation under both far-field and local (SNOM) illumination (photodoping). c)
Magnetic and electric field-induced ordering of stacks and study of their transport - Devices II: Photovoltaic cells – addressing the charge collection problem. a) Incorporation of SENMs carrying
donor/acceptor groups and capable of complementary mutual recognition in sandwich-type PVD structures. b)
Self-alignment of wires and incorporation in “bulk nanostructured films”. - Devices III: Organic nano-optoelectronic devices: supramolecular switches, single-photon emitters and
nanoelectromechanical actuators - Dissemination and strategic development
- Management, Internal reporting and strategic development
