for the investigations of the electrochemical fate of these compounds in different pH media. Computational chemistry was used as a tool to verify the experimental outcomes. Two chlorohydroxyanilines were found to oxidize at a potential lower than the standard antioxidant, ascorbic acid. The pH dependent oxidation indicated the involvement of protons during electron transfer reactions. The quasi-reversible
苯胺的衍生物有望用于可再充电电池,电致变色和生物传感器。酚和苯胺基化合物具有很强的抗氧化和抗癌活性。基于这些考虑,合成了三种新的氯羟基苯胺(CHA),并通过IR,13 C NMR,11 H NMR和UV-Vis光谱。循环,差分脉冲和方波伏安法用于研究这些化合物在不同pH介质中的电化学命运。计算化学被用作验证实验结果的工具。发现两种氯羟基苯胺的氧化电位低于标准抗氧化剂抗坏血酸。pH依赖的氧化表明质子在电子转移反应中的参与。第一和第二氧化峰的准可逆和不可逆性质由方波伏安法证明。峰电位与pH曲线的斜率以及半峰高处的宽度表示为1e和1H +参与每个氧化步骤。分子对接和紫外-可见光谱表明,所有的氯羟基苯胺都通过静电结合方式与DNA相互作用。灵敏的差分脉冲技术可以确定非常低的检测限。
