摘要：
A hexatopic C-3-symmetrical 5,5',5 ''-(((benzene-1,3,5-triyltris(azanediyl))tris(carbonyl))tris-(azanediyl))-triisophthalic acid (H-6-1) linker containing tri-urea groups has been designed and synthesized through the reaction between 1,3,5-benzenetriisocyanate and aniline, which was employed to construct a new copper(II) metal-organic framework (MOF Cu-TUH) under the solvothermal reaction with Cu(NO3)(2) in N,N-dimethylformamide. As expected, single crystal X-ray diffraction study reveals that the MOF Cu-TUH is composed of 3D packing of nanosized cuboctahedral, truncated tetrahedral, and truncated octahedral cages with a (3,24)-connected rht-topology. Furthermore, the preliminary gas uptake investigations of the activated MOF were conducted to evaluate its application in the area of gas storage and purifications. (C) 2015 Elsevier Ltd.
