摘要: Abstract A hexatopic C3-symmetrical 5,5′,5″-(((benzene-1,3,5-triyltris(azanediyl))tris(carbonyl))tris-(azanediyl))triisophthalic acid (H6-1) linker containing tri-urea groups has been designed and synthesized through the reaction between 1,3,5-benzenetriisocyanate aniline, which was employed to construct a new copper(II) metal–organic framework (MOF Cu-TUH) under solvothermal with Cu(NO3)2 in N,N-dimethylformamide. As expected, single crystal X-ray diffraction study reveals that MOF Cu-TUH is composed of 3D packing nanosized cuboctahedral, truncated tetrahedral, octahedral cages (3,24)-connected rht-topology. Furthermore, preliminary gas uptake investigations activated were conducted evaluate its application area storage purifications.
