以三唑类杀菌剂氟环唑为印迹分子,5-(4-甲基丙烯酰氧苯基)-10,15,20-三苯基卟啉锌为功能单体,乙二醇二甲基丙烯酸酯为交联剂,合成了新型的基于金属卟啉的分子印迹聚合物.紫外-可见光谱研究表明印迹分子与功能单体在聚合前形成1∶1配合物.通过选择性吸附和固相萃取表征研究了该印迹聚合物对氟环唑及具有类似化学结构的三唑类杀菌剂的识别能力,并与非印迹聚合物进行了比较,结果表明印迹聚合物具有良好的特异性识别性能,同时,印迹聚合物的交联度及吸附溶剂的极性对印迹效果有着显著影响.
Using triazole fungicide epoxiconazole as imprinting molecule and zinc 5- (4-methacryloyloxyphenyl) -10,15,20-triphenylporphyrin as functional monomer, ethylene glycol dimethyl Acrylate as crosslinking agent, a new type of metalloporphyrin-based molecularly imprinted polymer was synthesized.Ultraviolet-visible spectroscopy studies show that the imprinted molecule and the functional monomer form a 1: 1 complex before polymerization.According to the selective adsorption and solid phase Extraction Characterization The recognition ability of the imprinted polymers to epoxiconazole and triazole fungicides with similar chemical structure was studied and compared with that of non-imprinted polymers. The results showed that the imprinted polymers had good specific recognition performance, Meanwhile, the degree of cross-linking of the imprinted polymer and the polarity of the adsorbed solvent have a significant effect on the imprinting effect.
