【摘要】 研究了Al(i-PrO)3-H3PO4-en-EG体系中,两种具有AlP2O83-计量比的一维链AlPO-CSC和AlPO-ESC之间的结构转变,并对转变过程进行了粉末X射线衍射和组成分析。额外加入的酸或碱是两种链相互转变的推动力。由Al2P2四元环共顶点连接而成的AlPO-CSC链作为结构基元,与过渡金属离子Ni2+可以自组装成三维开放骨架NiAlP2O8·C2N2H9(NiAPO-1)。本工作提供了一种由低维结构定向构筑三维骨架结构的有效途径。更多还原

【Abstract】 In the Al(i PrO)3 H3PO4 en EG system, two one dimensional (1D) aluminophosphate chains AlPO ESC and AlPO CSC can transform to each other upon addition of some extra amount of en or H3PO4 to the reaction mixture. The transformation process has been studied by XRD and compositional analyses. IntroducingNi2+cations, the 1D AlPO CSC chain which acts as BU can be successfully assembled to 3D open framework NiAlP2O8·C2N2H9(NiAPO 1) by connecting the terminal phosphonyl oxygens with Ni2+species.更多还原
