Design and Synthesis of Pyridine Carboxylic Acid Ligand Polymers and Their Electrochemical Properties

通过溶剂热法合成{[Cu(5-hntaH)_(2)(en)]·2H_(2)O}n(5-hntaH_(2)=5-羟基烟酸,en=乙二胺)配位聚合物。配合物在管式炉通氩气的条件下,500℃恒温2 h,进行煅烧处理。分别以负载煅烧前后配合物的玻碳电极为工作电极,通过线性循环伏安、交流阻抗、计时电流、电极再生和差分脉冲等方法,测试煅烧前后该配位聚合物的电化学性质。结果表明,煅烧后的配位聚合物对催化多巴胺的响应效果良好。

{[Cu(5-hntaH)_(2)(en)]-2H_(2)O}n(5-hntaH_(2)=5-hydroxynicotinic acid,en=ethylenediamine)coordination polymers were synthesized by the solvothermal method.The coordination polymers were calcined at a constant temperature of 500℃ for 2 h under the condition of argon gas in a tube furnace.The electrochemical properties of the coordination polymers before and after calcination were tested by linear cyclic voltammetry,AC impedance,timing current,electrode regeneration and differential pulsing using a glassy carbon electrode loaded with the coordination polymers before and after calcination as the working electrode,respectively.The results showed that the calcined coordination polymer responded well to catalytic dopamine.
