Fluorescent polymers play an important role in bioimaging due to their improved brightness, inertness to microenvironment, and good biocompatibility. In this article, we used tetraphenylene (TPE) derivatives that give strong fluorescence emission in an aggregated state as fluorophores and synthesized fluorescent polymers via the covalent linkage of TPE-based rhomboidal Pt(II) metallacycles. Due to the integration of covalent linkage-induced aggregation of the monomers, the aggregation-induced emission character of TPE derivatives together with Pt(II)-based metal−ligand interactions, these polymers exhibit enhanced emission compared with their corresponding precursors, making them applicable as excellent cell imaging agents. Considering the potential anticancer activity of rhomboidal Pt(II) metallacycles, these polymers may serve as theranostic agents for both bioimaging and cancer therapy.
荧光聚合物由于其较高的亮度、对微环境的惰性和良好的生物相容性,在生物成像中发挥着重要作用。在本文中,我们使用四苯基(TPE)衍生物作为荧光物质,在TPE基菱形Pt(II)金属环的共价键连接下合成了荧光聚合物。由于单体的共价键诱导的聚集作用、TPE衍生物的聚集诱导发光特性以及Pt(II)基金属配体相互作用的整合,这些聚合物的发光强度比其对应的前体有所增强,使它们成为优秀的细胞成像试剂。考虑到菱形Pt(II)金属环具有潜在的抗癌活性,这些聚合物可能作为生物成像和癌症治疗的治疗诊断剂。
