Abstract

Two novel silica based lanthanide complexes (Tb(a)₂ and Eu(a)₂) were encapsulated into poly(acrylic acid) host. Both Tb(III) and Eu(III) containing hydrogels have typical and easily distinguished narrow line emissions occurring in the green and red region respectively. Particularly, the excitation wavelength for Eu complex can be extended into nearly visible light range (λ_ex = 395 nm). Interestingly, we discover that these target materials not only exhibit selective emission response towards HSO4^- ) (detection limit 10^-5 M) compared with CH₃COO^- , F^- , C^-) , Br) and I) but also give unique quenching to Cu²⁺ (detection limit 10^-5 M) (tested cations: Cu²⁺, Pd²⁺, Cd²⁺, Co²⁺ and Mn²⁺). More importantly, this kind of materials can be recycled more than 10 times.
