摘要

A new bismuth-based fluorous metal-organic framework, [Bi(OOCC6F5)(3)(C10H8N2)(H2O)(2)], (OOCC6F5 = pentafluorobenzoate, C10H8N2 =2,2'-bipyridine)(1) is synthesized by a hydrothermal method. Compound 1 crystalizes in the P2(1)/c space group, exhibiting a two-dimensional supramolecular architecture by intermolecular C-H center dot center dot center dot F-C interactions between the hydrogen atoms in 2,2'-bipyridine and fluorine atoms in adjacent perfluorophenyl rings. In addition, compound 1 shows excellent properties of degradation Congo red in the absence of UV-vis radiation. Moreover, adsorption kinetics study suggested that the adsorption of Congo red belongs to first-order reaction kinetics. Our results indicated that bismuth-based FMOFs could be promising candidates for the development of efficient degradation of organic dye.
