Abstract:Rare-earth(RE) complexes that own advantages of narrow f-f emission bands, long lifetime, large Stokes shifts and excellent paramagnets have received increasing attention in the field of biological detection, disease diagnosis and biological activity researches. However, it is still a serious challenge for RE complexes to exist in water media steadily because of poor solubility and fluorescence quench effect. In recent years, investigations have shown that the assembly of RE complexes into ordered two-dimensional or three-dimensional nanomaterials can effectively promote their dispersion in aqueous solutions and biological environments, and improve or stabilize their luminescence. In this review, we highlighted recent research progress in the assembly and bioimaging of RE complexes in aqueous solutions or biological environments, and discussed the application potential and corresponding challenges. It provides a theoretical basis and new perspectives for further researches on the assembly behavior and bioimaging function of RE complexes.
Keywords:rare-earth complexes  bioimaging  assembly
