摘　　要：以咪唑[4,5-f][1,10]-菲啰啉(phen)为母体,通过噻吩取代基的引入修饰合成单体L1。通过溶剂热法,单体L1与Zn^(2+)配位反应,合成了配合物a,其分子式为[Zn(phen)_(2)L1]·2ClO_(4)。抗藻实验结果表明,当配合物a的浓度≥5 mg/L时,其对海水小球藻、小新月菱形藻和三角褐指藻均具有较好的抑制生长效果;抗菌实验结果表明,配合物a对大肠杆菌和枯草芽孢杆菌均具有较好的抑菌活性和生长抑制效果,这是因为配合物a吸附在两种菌的细胞表面并导致细胞破碎,且配合物a使大肠杆菌的活性氧水平显著提高,从而导致其死亡;海洋挂板实验结果表明配合物a具有良好的防污性能。The monomer L1 is synthesized by modifying the thiophene substituent with imidazo[4,5-f][1,10]-phenanthroline as the parent,and the monomer L1 is ligated with Zn^(2+)by the solvothermal method to obtain the complex a,namely[Zn(phen)_(2)L1]·2ClO_(4),and the structure of L1 and complex a are characterized.The results of the anti-algae experiment show that when the concentration of complex a is≥5 mg/L,the growth of Chlorella salina,Nitzschia closterium f.minutissima and Phaeodactylum tricornutum can be greatly inhibited.The results of the antibacterial experiments show the complex a can well inhibit the growth of E.coli and Bacillus subtilis.The reason is that the complex a can be absorbed into the surfaces of the two bacteria,and contribute to cell disruption.Besides,the complex a causes a significant increase in the reactive oxygen level of E.coli,leading to their death.The antifouling performance of the complex a is proved to be good by the sea hanging board test.
