合成了9种3-(2-羟基萘基-1-偶氮)-1,2,4-三氮唑(HL1),3-(2,4-二羟苯基-1-偶氮)-1,2,4-三氮唑(HL2),3-(2-羟基-3-羧基萘基-1-偶氮)-1,2,4-三氮唑(HL3),3-(2-羟基-5-溴苯基-1-偶氮)-1,2,4-三氮唑(HL4)和3-(2-羟基-5-甲基苯基-1-偶氮)-1,2,4-1,2,4-三氮唑(HL5)的Zr(Ⅱ)配合物并用元素分析,摩尔电导,磁矩,IR,UV-Vis,1H-NMR以及热分析(TGA和DTA) 对其进行了表征.结果表明HL1-HL5以二齿一元配体方式通过偶氮的氮原子和羟基基团的氧原子与Zr(Ⅱ)离子配位生成单核配合物.用4种革兰氏阴性菌,即大肠杆菌(Escherichia coli),粘质沙雷氏菌(Serratiamarcescens),阴沟肠杆菌(Enterobacter cloacae)和普通变形杆菌(Proteus vulgaris),以及2种真菌,即白色念珠菌(candida albicans)和黑曲霉菌(Aspergillus niger)对配体及其配合物的生物学活性进行了研究.最小抑菌浓度(MICs)用纸上杯碟琼脂扩散法测定,结果表明在大多数情况下,金属化的配合物的抗微生物活性与自由配体相比有所增强.
