| 摘 要： | 合成了Eu3+的水杨酸和邻菲咯啉三元配合物,其组成为Eu(Hsal)3phen,用IR,UV,XPS研究配合物的性质和成键特征.结果表明,Hsal-的羧基、phen的两个氮原子均与Eu3+离子呈双齿配位,形成配合物后芳香环上的共轭性减小.用循环伏安法研究了配合物在玻碳电极上的电化学行为,发现配合物的电化学可逆性比游离Eu3+离子差,不同底液对配合物的电化学行为有影响.

Study on the Complex of Eu3+ with Salicylic Acid and 1,10-Phenanthroline |
| |
| Abstract: | A new solid ternary complex of Eu3+ with salicylic acid (H2sal) and 1,10 Phenanthroline(phen) was synthesized with its formula expressed as Eu(Hsal)3phen. Its properties were investigated by IR, UV spectrometry, XPS and cyclic voltammetry (CV). The spectra results indicate that both Hsal- and phen coordinate with Eu3+ by bidentate pattern, and that the conjugate character of aromatic ring decreases. The electrochemical reversibility of the complex is inferior to that of free Eu3+,and the background solution can influence the CV behavior of Eu(Hsal)3phen. |
