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 MnII complex into a Tb-III-containing polymer leads to greater fluorescence enhancement compared with the NiII complex, while the incorporation of the FeIII complex results in fluorescence quenching, thus the incorporation of different transition-metal complexes into the copolymers ensures tunability of the copolymer's fluorescence property.
