尽管芳香族化合物在有机化学中占据着中心地位，但反芳香族化合物几乎没有表现出实际用途。在此，我们报告了抗芳香族化合物作为可充电电池电极活性材料的应用。用锂金属阳极检查了二甲叉取代的去甲咯镍(II)络合物(NiNC)作为阴极活性材料的性能。 100次充放电循环后仍保持约207mAhg(-1)的最大放电容量。此外，NiNC的双极氧化还原特性使得能够构建无锂金属的可充电电池。 NiNC电池的高性能展示了稳定的抗芳香族化合物作为电极活性材料的前景特征。
Although aromatic compounds occupy a central position in organic chemistry, antiaromatic compounds have demonstrated little practical utility. Herein we report the application of an antiaromatic compound as an electrode-active material in rechargeable batteries. The performance of dimesityl-substituted norcorrole nickel(II) complex (NiNC) as a cathode-active material was examined with a Li metal anode. A maximum discharge capacity of about 207mAhg(-1) was maintained after 100 charge/discharge cycles. Moreover, the bipolar redox property of NiNC enables the construction of a Li metal free rechargeable battery. The high performance of NiNC batteries demonstrates a prospective feature of stable antiaromatic compounds as electrode-active materials.
