Several zirconium phosphonates, Zr(O3PR)2 (R = (CH2)3COOH, CH2C6H5, (CH2)2Cl, CHCH2, (CH2)2CHCH2), containing reactive functional groups were synthesized and structurally characterized. There were found to be nonreactive toward incorporation of small molecules and ions from solution. In an effort to synthesize microporous phosphonates, mixed phosphonates of composition Zr(O3PCH2C6H5)x(O3PCH3)2-x and
几个锆膦酸盐,锆(O 3 P - [R )2(- [R =(CH 2)3 COOH,CH 2 Ç 6 ħ 5,(CH 2)2氯,CHCH 2,(CH 2)2 CHCH 2),合成了含有反应性官能团并对其结构进行了表征。发现与溶液中的小分子和离子结合没有反应。为了合成微孔膦酸酯,组成为Zr(O 3 PCH 2 C 6)的混合膦酸酯制备H 5)x(O 3 PCH 3)2- x和Zr(O 3 P(CH 2)3 COOH)x(O 3 POH)2- x,将x从0改变为2。苄基/甲基衍生物表明烷基部分在整个层间通道中无规分布,导致相对多孔的材料。观察到的3-羧丙基/羟基材料的层间间距表明其中烷基被分离的产物,导致较少的孔隙率。讨论了多孔和无孔材料的结构模型。
