BNB-doped phenalenyls – aromaticity switch upon one-electron reduction. Issue 19 (5th February 2021) - Crumbach, Merian
Abstract : Fully aromatic, fluorescent, and highly robust BNB-doped phenalenyls were prepared via ring expansion, which undergo an aromaticity switch upon reduction. Abstract : Fully aromatic, luminescent, and highly robust BNB-doped phenalenyls have been prepared, which are isoelectronic to the phenalenyl cation. B -Fluoromesityl-substitution leads to fluorescence in an extremely narrow range and significant increase in the reduction potential. Detailed theoretical investigations revealed an intramolecular aromaticity switch upon one-electron reduction.
