Abstract

Summary: In this study, a terbium‐complex monomer and transition‐metal‐complex monomers (Fe^III^, Mn^II^, and Ni^II^ complex monomers) are synthesized, and novel acrylate copolymers are then obtained through covalent attachment of the terbium complex and the transition‐metal complex onto the macromolecular chain simultaneously. The copolymers developed herein present the characteristic fluorescence properties of the terbium(III) ion, The incorporation of an Mn^II^ complex into a Tb^III^‐containing polymer leads to greater fluorescence enhancement compared with the Ni^II^ complex, while the incorporation of the Fe^III^ complex results in fluorescence quenching, thus the incorporation of different transition‐metal complexes into the copolymers ensures tunability of the copolymer's fluorescence property.
