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.
已制备出全芳香、发光且高度稳定的硼氮共掺杂苊烯，它们与苊烯阳离子等电子。硼-氟代均三甲苯基取代导致荧光范围极窄且还原电位显著增加。详细的理论研究揭示了单电子还原时的分子内芳香性开关。
