在有机电致发光器件中，含有苯甲酸锂的器件是所有研究器件中性能最好的。通过重氮化学将苯甲酸锂的芳香多层膜共价连接到天然石墨表面，所得石墨作为锂离子电池的阳极材料表现出优异的电化学性能。 Among organic electroluminescent devices, devices containing lithium benzoate have the best performance among all studied devices. The aromatic multilayer film of lithium benzoate was covalently connected to the surface of natural graphite through diazotization chemistry, and the resulting graphite exhibited excellent electrochemical performance as an anode material for lithium-ion batteries.
