Abstract
In recent years, heterogeneous catalysis has become one of the most active domains in the research of metal–organic frameworks (MOFs). Here, two three-dimensional (3D) Co(II)-MOFs with open metal sites and exposed azo functionality on the MOF backbone have been constructed via mixed ligand assembly. Both the MOFs, 1 {[Co2(1,4-NDC)2(L)(H2O)2(μ2-H2O)]·(DMF)2(H2O)}n and 2 {[Co(fma)(L)(H2O)2]·S}n [1,4-NDC = 1,4-naphthalene dicarboxylic acid, fma = fumaric acid, L = 3,3′-azobis pyridine and S = disordered solvents] exhibit 3D frameworks with metal-bound aqua ligands. These metal-bound aqua ligands, as well as the lattice solvent molecules, could simply be removed upon activation affording the desolvated frameworks 1a and 2a respectively maintaining the original crystallinity with a varying number of open metal sites. Although crystallographic analysis revealed a porous structure for both the MOFs (34.4% and 14.3% void volume for 1 and 2, respectively), 1 showed a permanently microporous nature with a Brunauer–...
