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 Å(3) 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.
通过分别将氯化铜、5-四唑基间苯二甲酸（H3TZI）与各种Keggin型多金属氧酸盐（POMs）进行简单的一步溶剂热反应，分离得到了一系列三种引人注目的配合物：[PMo12O40]@[Cu6O(TZI)3(H2O)9]4·OH·31H2O（H3TZI = 5-四唑基间苯二甲酸；记为HLJU-1，HLJU = 黑龙江大学）、[SiMo12O40]@[Cu6O(TZI)3(H2O)9]4·32H2O（记为HLJU-2）和[PW12O40]@[Cu6O(TZI)3(H2O)6]4·OH·31H2O（记为HLJU-3）。HLJU 1-3的晶体分析表明，Keggin型多金属氧阴离子紧密地嵌入到rht-MOF-1（MOF：金属有机框架）的笼中，其晶胞体积较大，在87968-88800 Å(3)范围内，孔隙率约为68%。HLJU 1-3在水相中温和条件下用环境友好型氧化剂氧化烷基苯时表现出独特的催化选择性和反应活性，以及对水溶液中有机污染物的吸附能力。
