采用水热合成手段，以磷钼酸为多金属氧酸盐（简称多酸）建筑块，三苯基膦为有机配体，通过自组装的方式制备了一种无机?有机杂化化合物，通过X?射线单晶衍射技术确定其分子式为H15{(PMo12O40)2[MoO4?(PPh3)4]2[NaO3?(PPh3)3][(H2O?PPh3)3]（化合物1）。该化合物是由[PMo12O40]3-、[MoO4?(PPh3)4]2-、[NaO3?(PPh3)3]5-和H2O?PPh3建筑块之间通过静电作用力形成的一种新型无机?有机杂化材料。测试了该化合物的红外光谱、发光光谱、循环伏安特性曲线，重点研究了该化合物的光催化降解亚甲基蓝(MB)的性质。光降解实验结果表明，该化合物具有良好的降解有机染料的能力。

Under the hydrothermal synthesis,an organic?inorganic hybrid compound was prepared through the self?assembly process by using phosphomolybdic acid as a polyoxometallate (polyacid for short) building block and triphenylphosphine as an organic ligand.Its molecular formula was determined by X?ray single?crystal diffraction technique as H15{(PMo12O40)2[MoO4?(PPh3)4]2?[NaO3?(PPh3)3][(H2O?PPh3)3]（compound 1),which is a novel inorganic?organic hybrid material formed by electrostatic interactions between [PMo12O40]3-,[MoO4?(PPh3)4]2-,[NaO3?(PPh3)3]5- and H2O?PPh3 building blocks.The IR spectrum,luminescence spectra and cyclic voltammetric characteristic curves of compound 1 were also tested,focusing on the photocatalytic degradation of methylene blue(MB).The good ability of compound 1 to degrade organic dyes was demonstrated by photodegradation analysis experiments.
