用氯化铜、5-四氮唑邻苯二甲酸（H3TZI）和各种keggin型多金属氧酸盐（POMs）进行简单一步溶剂热反应，分别分离得到了一系列优异的配合物[PMo12O40]@[cu60 (TZI)3(H2O)9]4·OH·31H2O （H3TZI = 5-四氮唑邻苯二甲酸；H3TZI =黑龙江大学）、[SiMo12O40]@[cu60 (TZI)3(H2O)9]4·OH·31H2O （HLJU-3）和[PW12O40]@[cu60 (TZI)3(H2O)6]4·OH·31H2O （HLJU-3）。HLJU 1−3的晶体分析表明，keggin型多氧阴离子在rht-MOF-1 （MOF：金属-有机骨架）的笼中被紧密地贴合在一起，其胞体体积在87968−88800 Å3范围内，孔径约为68%。HLJU 1-3在温和的水相条件下对环境良性氧化剂氧化烷基苯表现出独特的催化选择性和反应活性，并对水溶液中的有机污染物具有吸收能力。
A series of three remarkable complexes [PMo12O40]@[Cu6O(TZI)3(H2O)9]4·OH·31H2O (H3TZI = 5-tetrazolylisophthalic acid; denoted as HLJU-1, HLJU = Heilongjiang University), [SiMo12O40]@[Cu6O(TZI)3(H2O)9]4·32H2O (denoted as HLJU-2), and [PW12O40]@[Cu6O(TZI)3(H2O)6]4·OH·31H2O (denoted as HLJU-3) have been isolated by using simple one-step solvothermal reaction of copper chloride, 5-tetrazolylisophthalic acid (H3TZI), and various Keggin-type polyoxometalates (POMs), respectively. Crystal analysis of HLJU 1−3 reveals that Keggin-type polyoxoanions have been fitted snuggly in the cages of rht-MOF-1 (MOF: metal−organic framework) with large cell volume in a range of 87968−88800 Å3 and large pore volume of about 68%. HLJU 1–3 exhibit unique catalytic selectivity and reactivity in the oxidation of alkylbenzene with environmental benign oxidant under mild condition in aqueous phase as well as the uptake capacity towards organic pollutants in aqueous solution.
