Antiaromatic Frameworks
Compounds with 4n pi-electrons (n = 1, 2, 3, …) have recently received significant attention due to their unique optical and electronic properties – but they are not very stable.
The group of Oliver Dumele synthesized the first antiaromatic framework materials and obtained three highly crystalline and porous Covalent Organic Frameworks (COFs).
In collaboration with Prof. List-Kratochvil (HUB) and Prof. Birgit Esser (Univ. Ulm), it was shown that this material is photoconductive upon irradiation with visible light. Investigations as battery electrode materials demonstrate enhanced charge storage capabilities compared to a classic aromatic framework. The results propose antiaromaticity as a new design principle for functional materials.
