Synthesis And Co2 Adsorption Properties Of Hydrophobic Porous Coordination Polymer Featuring [Zn-9(Mebtz)(12)](6+) Building Units

A hydrophobic porous coordination polymer, [Zn-9(MeBTZ)(12)(BPDC)(3)] where MeBTZ is 5-methylbenzotriazolate and BPDC is 4,4'-biphenyldicarboxylate, was obtained through a one-pot solvothermal reaction of zinc nitrate hexahydrate, 5-methyl-1H-benzotriazole and 4,4'-biphenyldicarboxylic acid in N,N-dimethylacetamide. The structure of [Zn-9(MeBTZ)(12)(BPDC)(3)] was built from trigonal antiprismatic [Zn-9(MeBTZ)(12)](6+) nodes connected with linear BPDC linkers, having 4(6)6(9) net topology. The working capacity for CO2 adsorption on [Zn-9(MeBTZ)(12)(BPDC)(3)] over the pressure range between 0.1 and 1.6 MPa at 40 degrees C was 3.4 mol kg(-1) after the preintroduction of high humidity.
