摘要：
Two lanthanide-based metal–organic frameworks with flexible alicyclic carboxylate ligands, generally formulated as [Sm(TMG)(HTMG)(H2O)] (1) and [Nd2(CHDC)3(H2O)] (2), have been successfully synthesized and characterized. They represent the first example of lanthanide-TMG and lanthanide-CHDC systems. Their structures range from 1D infinite chains to 2D extended layer structure. Complexes 2 exhibit strong fluorescent emissions in the near-infrared region at room temperature. Interestingly, the structural difference between compounds 1 and 2 indicates the pH values have subtle influence on the coordination modes of ligands and dimension of LMOFs.
