合成了具有内在光响应特性的选择性、稳定的分子印迹聚合物，用于预定配体的光调节结合。高交联，独立的聚合物膜合成从两个交联剂的优化混合物-乙二醇二甲基丙烯酸酯和四甘醇二丙烯酸酯。对苯偶氮丙烯酰苯胺（PhAAAn）作为一种新型的光响应功能单体，用于合成分子印迹聚合物。PhAAAn在聚合物膜内的光异构化的动力学的研究之前和之后的处理与各种介质显示出优异的功能稳定性的膜。在模板丹磺酰胺存在下合成的聚合物膜具有识别丹磺酰胺的选择性位点，并且这些位点的亲和力可以通过用紫外光或可见光照射而可逆地改变。
Selective, stable, molecularly imprinted polymers having intrinsic photoresponsive properties were synthesized for the purpose of photoregulated binding of a predetermined ligand. Highly crosslinked, free-standing polymer membranes were synthesized from an optimized mixture of two cross-linkers-ethylene glycol dimethacrylate and tetraethylene glycol diacrylate. For synthesizing molecularly imprinted polymers, p-phenylazoacrylanilide (PhAAAn) was used as a new photoresponsive functional monomer. A study of the kinetics of photoisomerization of PhAAAn within the polymer membranes before and after treatment with various media showed the excellent functional stability of the membranes. Polymer membranes synthesized in the presence of the template dansylamide possess selective sites for recognizing dansylamide, and the affinity of these sites can be reversibly changed by illumination with ultraviolet or visible light.
