摘要

采用元素分析、电导率测量、磁化率、红外光谱分析和溶解度等方法，合成了以 2-羟基-1-萘醛和对甲氧
基苯胺为原料的 Co（II）和Zn（II）与席夫碱的金属配合物，并对其进行了表征测试。评价席夫碱及其相应的金属
配合物的抗氧化活性。摩尔电导值范围（6.62-7.80Ω-1cm2mol-1）表明配合物的非电解性质。磁化率值表明，Co
（II）配合物是顺磁性的，而Zn（II）配合物是抗磁性的。红外光谱分析表明，席夫碱表现为双齿配体。元素分析结
果显示，在席夫碱和金属配合物中观察到的和计算出的 C、H和N的百分比略有不同，发现所有配合物中的金属配
体比为 1：2。席夫碱及其配合物的抗氧化活性是基于 1，1-二苯基-2-苦基-肼基（DPPH）-自由基活性的自由基
清除作用来测量的。结果表明，席夫碱及其金属配合物表现出优异的抗氧化性能。
