在乙醇水溶液介质中,60℃水浴加热的条件下,合成了标题化合物。经络合滴定、摩尔电导、元素分析、红外光谱、紫外光谱、热重-差热和循环伏安等测试对配合物进行了表征,确定配合物的化学组成为:[Ce(Ⅲ)(His)3phen]Cl3·3H2O。重点通过循环伏安测定了配合物在玻碳工作电极上的电化学行为,在HAc-NaAc缓冲溶液(pH约为6.0)中配合物{[Ce(Ⅲ)(His)3phen]Cl3·3H2O}和CeCl3·7H2O在-0.3～-1.0 V(vs.SCE)电位范围内均表现出电化学活性,配合物的电化学活化中心是Ce3+,该配合物为准可逆体系,在扫描速率0.05～0.2 V/s范围内,配合物的还原峰电流与扫描速率的平方根呈现很好的线性关系。
The title compound was synthesized under heating in a 60 ° C water bath in an aqueous ethanol medium. The complex was characterized by means of complexometric titration, molar conductance, elemental analysis, IR, UV, TG-DTA and cyclic voltammetry. The chemical composition of [Ce (Ⅲ) ) 3phen] Cl3 · 3H2O. The electrochemical behavior of the complex was investigated by cyclic voltammetry at the glassy carbon electrode. The complex of {[Ce (Ⅲ) (His) 3phen] Cl3 · 3H2O} in HAc-NaAc buffer solution And CeCl3 · 7H2O showed electrochemical activity in the potential range of -0.3 ~ -1.0 V (vs.SCE). The electrochemically active center of the complex was Ce3 +. The complex was a quasi-reversible system with a scan rate of 0.05 ~ 0.2 In the range of V / s, the complex peak current and the square root of the scan rate showed a good linear relationship.
