Fluorine makes the difference! Bis(2,2′‐biphenoxy)borates decorated with fluorine substituents have been synthesized and studied in supercapacitor test cells (see scheme). A clear trend towards higher electrochemical stability with the increase of the fluorine content has been observed. For a maximum performance, only two fluorine substituents per benzene moiety are required.
氟与众不同!合成有氟取代基的双(2,2'-联苯氧基)硼酸盐已在超级电容器测试电池中进行了合成和研究(请参阅方案)。观察到明显的趋势,即随着氟含量的增加,电化学稳定性更高。为了获得最佳性能,每个苯部分仅需要两个氟取代基。
