A cadmium(II) 3-D porous metal-organic framework, (Me2NH2)(4) inverted right perpendicularCd(2)(TTCA)(2)Cl(2)inverted left perpendicular center dot 7DMF center dot 2Diox center dot 6H(2)O (1) (TTCA = triphenylene-2,6,10-tricarboxylate, DMF = N,N-dimethylformamide, diox = 1,4-dioxane), has been synthesized through solvothermal conditions. Single-crystal X-ray analysis reveals that the structure of 1 has a two-fold interpenetrating framework with a large solvent-accessible volume of 52% per unit cell. The result of topological analysis shows that 1 is a (3,3)-connected 3-D network with {10(3)} topology. Luminescence tests illustrate that 1 can selectively sense nitroaromatic explosives via a luminescence quenching mechanism.
