Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Two electroactive materials, <bold>M1</bold> and <bold>M2</bold>, are synthesized and their fluorescent electropolymerized (EP) films are prepared and used to detect metal ions. From the tested metal ions, <bold>M1</bold> and <bold>M2</bold> are demonstrated to be sensitive and selective for Fe³⁺ ions. In particular, <bold>M2</bold> exhibits higher sensitivity towards Fe³⁺ ions. The fluorescent detection ranges from 10⁻⁵ <sc>M</sc> to 4×10⁻⁴ <sc>M</sc>. The excellent performance of the EP fluorescent films is mainly due to the strong metal‐chelated properties of <bold>M2</bold> and 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.</p> </abstract>
