Encapsulation and Sensitization of UV–vis and Near Infrared Lanthanide Hydrate Emitters for Dual- and Bimodal-Emissions in Both Air and Aqueous Media Based on a Porous Heteroatom-Rich Cd(II)-Framework

A porous heteroatom-rich Cd(II)-polymeric framework which is generated from an ethylene glycol ether-bridging dicarboxylate ligand L, 4,4′-bipy and Cd(II) ion is reported. It contains one-dimensional tubes (9–11 Å) which are able to trap cationic lanthanide hydrates such as Eu(H2O)8 3+, Tb(H2O)8 3+,...

Description
Summary:A porous heteroatom-rich Cd(II)-polymeric framework which is generated from an ethylene glycol ether-bridging dicarboxylate ligand L, 4,4′-bipy and Cd(II) ion is reported. It contains one-dimensional tubes (9–11 Å) which are able to trap cationic lanthanide hydrates such as Eu(H2O)8 3+, Tb(H2O)8 3+, and Nd(H2O)8 3+ under ambient conditions to generate Ln(H2O)8 3+-loaded materials. In addition, the heteroatom-rich host material can effectively protect and sensitize the encapsulated Ln3+ emitters in their hydrate form in both air and aqueous media. Furthermore, the dual- and bimodal-emissions are successfully realized by intercalation of the different Ln3+-hydrates based on a guest-driven approach.
