摘　　要：使用羧基蒽醌与氨基酸通过酰胺键或脲键进行酰胺缩合反应,以及卤代蒽醌和胺的偶联反应两种方法,分别合成两种具有氨基酸官能团的蒽醌衍生物,即(4,5-二羟基-9,10-蒽醌-2-羰基)-谷氨酸(GAAQ)和N,N′-(9,10-蒽醌-2,6-二羧基)-二-甘氨酸(GLAQ)。研究GAAQ和GLAQ两种蒽醌衍生物的电化学性质以及GLAQ的单电池循环性能。结果表明,GLAQ作为电池负极电解液活性物质与亚铁氰化钾组成碱性液流电池,以Nafion作为离子交换膜,在200 mA/cm^(2)的电流密度下进行充放电循环试验,开路电压大于1 V,库伦效率可达92%,电压效率高于85%,能量效率高于80%,并且在200次循环中没有明显的容量下降。Two anthraquinone derivatives with amino acid functional groups were synthesized by two methods:the amide condensation reaction of carboxyl anthraquinone with amino acids by amide bond or urea bond,and the coupling reaction of halogenated anthraquinone with amine,that is,(4,5-dihydroxy-9,10-anthraquinone-2-carbonyl)-glutamic acid(GAAQ)and N,N′-(9,10-anthraquinone-2,6-dicarboxylic)-di-glycine(GLAQ).The electrochemical properties and single cell cycling performance of two anthraquinone derivatives,GAAQ and GLAQ,and the cycling performance of GLAQ were investigated.Among them,GLAQ was an alkaline flow battery composed of the negative electrode electrolyte active substance and potassium ferrocyanide.Using Nafion as the ion exchange membrane,charge and discharge cycling experiments were conducted at a current density of 200 mA/cm^(2).The results showed when the open circuit voltage was greater than 1 V,the Coulombic efficiency was 92%,the voltage efficiency was higher than 85%,and the energy efficiency was higher than 80%.There was no significant capacity decrease in 200 cycles,which indicated that GLAQ had good application prospects for active substances in flow battery.
