摘要	["Two isoreticular lanthanide metal-organic frameworks (Ln-MOFs), {[Ln2(H2O)6(H2dobdc)612H2O}n (Ln = Tb3+ and Gd3+); H4dobdc = 2,5-di-hydroxy-benzene-1,4-di-carboxylic acid), constructed from a hydroxy-functionalized dicarboxybenzene were synthesized and structurally characterized. Single-crystal X-ray crystallography reveals that the two Ln-MOFs were constructed from Ln3+ dimers as secondary building units, which were linked by H2dobdc2- ligands to form three-dimensional (3D) frameworks featuring pcu topology. Interestingly, 1D triangular porous channels were formed in the frameworks with a high density of coordinated and guest water molecules and hydroxy-containing inwall, which provide a hydrophilic and highly oxygenated environment. Magnetic studies indicated the Tb(iii) analogue exhibited slow relaxation of magnetization under an applied static field of 2 kOe while the Gd(iii) MOF displayed the magnetocaloric effect (MCE) with a magnetic entropy change of 19.5 J kg-1 K-1. At 55 degrees C under 98% RH, impedance spectroscopy indicated that the Ln-MOFs exhibit high proton conductivities up to 1.63 x 10-2 and 2.51 x 10-2 S cm-1 through the vehicle mechanism, suggesting that the two are highly proton-conducting Ln-MOFs. This work not only demonstrates two rare magnetic-electrical bifunctional Ln-MOFs with high proton-conduction and interesting magnetic properties but also provides potential design guidelines for high-performance Ln-MOF based proton conductors.","Two Tb(iii) and Gd(iii) MOFs synthesized through a hydroxy-functionalized dicarboxybenzene were reported to show conductivities up to the 10-2 S cm-1 level with slow magnetic relaxation and magnetocaloric effect."]
