通过分子印迹证明了在聚合物材料中以面对面方式排列两个卟啉部分的策略，其中卟啉Zn(II)络合物单体在吡嗪或1,5-萘啶作为模板分子存在下与乙二醇二甲基丙烯酸酯交联。在使用所得印迹聚合物作为固定相的色谱研究中，两种聚合物都显示出对原始模板分子的选择性，表明两个锌卟啉部分以面对面的方式固定，并且中心对齐用于吡嗪识别，偏移排列用于1,5-萘啶识别。具有卟啉部分的印迹聚合物还显示出其荧光强度随着目标分子的浓度而降低，这表明其作为传感材料的潜在用途。 (C) 2009 Elsevier B.V. 保留所有权利。
A strategy for arranging two porphyrin moieties in a face-to-face fashion in polymeric material was demonstrated by molecular imprinting, whereby porphyrin Zn(II) complex monomers were cross-linked with ethylene glycol dimethacrylate in the presence of pyrazine or 1,5-naphthyridine as a template molecule. In chromatographic studies using the resultant imprinted polymers as stationary phase, both the polymers showed selectivity for the original template molecule, suggesting that two zinc porphyrin moieties were immobilized in the face-to-face fashion, and were center-aligned for pyrazine recognition and offset-arranged for 1,5-naphthyridine recognition. The imprinted polymer with porphyrin moieties also showed a decrease in its fluorescence intensity in response to the concentration of the target molecule, suggesting the potential utility as sensing material.
