合成了两种电活性材料m1和m2，制备了它们的荧光电聚合（EP）膜，并将其用于检测金属离子。从测试的金属离子来看，m1和m2对Fe3+离子具有敏感性和选择性。特别是，m2对Fe3+离子表现出更高的灵敏度。荧光检测范围为10−5m ~ 4×10−4M。环氧乙烷荧光膜的优异性能主要是由于环氧乙烷的强金属螯合性能和环氧乙烷膜固有的多孔交联网络结构。因此，该研究提供了一种有前途的Fe3+传感候选材料和一种潜在的荧光传感膜制备方法。
Two electroactive materials,M1andM2, are synthesized and their fluorescent electropolymerized (EP) films are prepared and used to detect metal ions. From the tested metal ions,M1andM2are demonstrated to be sensitive and selective for Fe3+ions. In particular,M2exhibits higher sensitivity towards Fe3+ions. The fluorescent detection ranges from 10−5Mto 4×10−4M. The excellent performance of the EP fluorescent films is mainly due to the strong metal‐chelated properties ofM2and the intrinsic porous cross‐linked‐network microstructure of the EP films. This study, thus, provides a promising Fe3+sensing candidate and a potential preparation method for fluorescent sensing films.
