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.
已经制备了完全芳族的,发光的和高度健壮的BNB掺杂的苯
菲烯,其与苯
菲烯阳离子是等电子的。B-荧光基团取代导致荧光在非常窄的范围内,并且还原电位显着增加。详细的理论研究表明,单电子还原后分子内的芳香性会发生变化。
