Abstract
Reaction of AlCl(3)·6H(2)O with 2,2'-bipyridine-5,5'-dicarboxylic acid (H(2)bpydc) affords Al(OH)(bpydc) (1, MOF-253), the first metal-organic framework with open 2,2'-bipyridine (bpy) coordination sites. The material displays a BET surface area of 2160 m(2)/g and readily complexes metals to afford, for example, 1·xPdCl(2) (x = 0.08, 0.83) and 1·0.97Cu(BF(4))(2). EXAFS spectroscopy performed on 1·0.83PdCl(2) reveals the expected square planar coordination geometry, matching the structure of the model complex (bpy)PdCl(2). Significantly, the selectivity factor for binding CO(2) over N(2) under typical flue gas conditions is observed to increase from 2.8 in 1 to 12 in 1·0.97Cu(BF(4))(2).Entities:
