由季鏻盐与钼酸铵在常温条件下合成了含季鏻阳离子的(n-C_5H_(10)Ph_3P)_2[Mo_6O_(19)]多酸化合物,并通过X-射线单晶衍射、红外光谱、紫外光谱、热重分析和电化学对其进行了表征。季鏻配体上的氢原子通过与多酸阴离子端基氧原子形成氢键而构筑了一维链状结构,并且相邻季鏻配体上的苯环通过π-π作用形成三维层状结构。此外,对该多酸化合物的光催化降解亚甲基蓝的性能进行了研究。
The (n-C_5H_ (10) Ph_3P) _2 [Mo_6O_ (19)] polyacid compounds with quaternary phosphonium cation were synthesized from quaternary phosphonium salt and ammonium molybdate at room temperature. Their structures were characterized by X-ray single crystal diffraction, UV spectroscopy, thermogravimetric analysis and electrochemical characterization. The hydrogen atoms on the quaternary phosphonium ligand form a one-dimensional chain structure by forming hydrogen bonds with the polyoxoanion terminal oxygen atoms, and the benzene rings on the adjacent quaternary phosphonium ligands form a three-dimensional layered structure through π-π interaction . In addition, the photocatalytic degradation of methylene blue by this polyacid compound was investigated.
