| Project Detail |
SUPER will develop functional, self-assembled multi-quantum wells based on metal halide perovskites (MHPs) and organic semiconductors integrated at the molecular level in ordered extended solids, creating a hybrid material platform fully exploiting synergistic interactions between the organic and inorganic sublattices with an unprecedented level of sophistication. The resulting materials will have radically enhanced charge transport, improved luminescence yield and extended tunability compared to currently available MHPs, while providing new solutions to the main challenges of toxicity and stability faced by the entire field of MHPs. SUPER will undertake an original supramolecular approach creating a new fundamental understanding of how large molecular and atomic systems interact to form functional superstructures, merging concepts from organic and inorganic synthesis, solid-state chemistry, photophysics, organic electronics and device engineering. The bottom-up construction will start from the synthesis of innovative semiconductor molecular rods with widely tunable energetics allowing fine tuning of the internal energy level alignment, while encoding the structural characteristics regulating intermolecular associations and the controlled supramolecular assembly of the hybrid material. Solid-state nuclear magnetic resonance will be applied as top-notch technique to probe the low-dimensional phases, their defectivity, structural rigidity and local coordination environment with atomic-scale resolution. Advanced optical spectroscopy and charge transport measurements will assess the efficacy of the synthetic strategies establishing a close structure-properties relationship and assisting the material?s refinement. Light-emitting diodes and field-effect transistors will be used as final platforms to assess the concerted effect of supramolecular architecture, transport and luminescent properties ensuring the high-technological relevance of the newly-developed materials. |
