Three new lanthanide metal organic frameworks (LnMOFs), [HNMe(2)][Ln(2)(m-BDC)(3)(phen)(2)](Ln = Eu 1, Gd 2, Tb 3, m-H(2)BDC = 1,3-benzenedicarboxylic acid, phen = 1,10-phenanthroline), have been solvothermally synthesized through self-assembly reactions. Complexes 1-3 are isostructural and possess 3D architectures based on the octahedral [Ln(2)(COO)(6)] SBUs with a pcu net topology. Photoluminescence measurements show that 1 and 3 are highly emissive at room temperature with quantum yields of 86.87% (at 330 nm) and 85.62% (at 345 nm), respectively, and may be good candidates for light-emitting diodes (LEDs) and light applications. The magnetic properties of 2 and 3 have also been investigated through the measurement of their magnetic susceptibilities over the temperature range of 2-300 K. (C) 2011 Elsevier B.V.
