3D lanthanide metal–organic frameworks constructed from lanthanide formate skeletons and 3,5-bis(4′-carboxy-phenyl)-1,2,4-triazole connectors: synthesis, structure and luminescence

Three isomorphic lanthanide metal-organic frameworks (Ln-MOFs) have been constructed from lanthanide formate skeletons and 3,5-bis(4'-carboxy-phenyl)-1,2,4-triazole (H(2)bct) connectors. Further, by adjusting the co-doping ratio of different Ln(3+) ions into the framework, two doped Ln-MOFs are synthesized and show tunable luminescence emission including white-light emission.
