文摘

Two novel coordination polymers formulated as [Ln(L)(DMF)]_n [Ln = Tb (1), Dy (2); DMF = N, N-dimethylformamide, H₃L = 5?carboxyl-[1,1?3?1?terphenyl]-4,4?dicarboxylic acid] have been synthesized under solvothermal conditions. Structural analyses reveal that the two compounds are isostructural, and each forms a three-dimensional (3D) structure possessing one-dimensional (1D) channels filled with coordinated DMF molecules. 1D infinitely inorganic lanthanide chains are linked in parallel to each other by L^{3 ?/sup> ligands in [1, ?#xA0;1, 2] and [5, 7, 3] directions, leading to 3D frameworks. Moreover, the photoluminescence properties of 1 and 2 have been investigated. The resulting materials show strong solid-state emissions in the visible region at room temperature.}
