In this work, we present the synthesis of a novel Zn-Salphen complex containing an allyl group, which was used as building block in the further preparation of a new family of functional terpolymers. These polymers were obtained through radical co-polymerization with methyl metacrylate (MMA) and -butyl acrylate (BuA) in different ratios. The supramolecular recognition behavior of each polymer was evaluated via potentiometric measurements against selected anions in aqueous media. Interestingly, this proof of concept study shows that these systems were selective against only fluoride (F) or both, fluoride and acetate (OAc), by tailoring the relative content of Zn-Salphen monomer, thus making them a promising starting point for modular design of chemical sensors through straightforward synthetic approaches.
在这项工作中，我们合成了一种新型的含有烯丙基基团的 Zn-Salphen 配合物，该配合物可用作进一步制备新型功能三聚物的结构单元。这些聚合物通过与甲基丙烯酸甲酯（MMA）和 - 丁基丙烯酸酯（BuA）在不同比例下的自由基共聚得到。通过在水介质中对选定的阴离子进行电位测定，评估了每种聚合物的超分子识别行为。有趣的是，这项概念验证研究表明，通过调整 Zn-Salphen 单体的相对含量，这些体系可以对仅氟化物（F）或氟化物和醋酸盐（OAc）进行选择性识别，从而为通过直接的合成方法设计化学传感器提供了有前途的起点。
