Project description
New hybrid porphyrin structures hold promise for molecular electronics
Porphyrins are aromatic macrocycles composed of four nitrogen-containing rings joined by carbon bridges. Owing to their special functional properties, they play a central role in photosynthesis and in the creation of haemoglobin, a type of protein in red blood cells that transports oxygen throughout the body. Funded by the Marie Skłodowska-Curie Actions programme, the CarboPorph project will build on recent advancements in supramolecular porphyrin systems and polyyne chemistry to create and study novel hybrid compounds: cyclocarbon–porphyrin nanorings. Researchers will investigate the most efficient methods for synthesising macrocyclic compounds with varying sizes and different peripheral substituents. These new hybrid compounds could be used as functional materials in molecular electronics.
Objective
The proposed project combines recent advancements in supramolecular porphyrin systems and polyyne chemistry to create and study novel hybrid compounds: carbo-porphyrin nanorings. This will include extensive synthetic work to find the most efficient working schemes for macrocyclic compounds with varying sizes and different peripheral substituents, while minimizing linear polymerization. Specific choice of the building blocks will be guided by computer-aided design to ensure appropriate connectivity and steric demands for subsequent cyclooligomerizations. The size selectivity will be further refined by using template-assisted covalent self-assembly utilizing differently coordinating templates. The electronic and magnetic nature of the target compounds will be studied in solution using a range of techniques, including Nuclear Magnetic Resonance spectroscopy, UV-vis-NIR absorption and fluorescence spectroscopy and electrochemical methods, additionally characterized with X-ray crystallography in the solid state. These efforts will be focused on exploring global aromatic and antiaromatic currents in the neutral and oxidized forms of the macrocycles, gaining insight into the nature of aromaticity in nanometer-size pi-conjugated systems and contributing to the design of future functional materials.
