| 中文摘要: |
| 通过使用季鏻盐与钼酸铵在常温条件下合成了含季鏻阳离子的(n-PentylPh3P)2[Mo6O19]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。产物中的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,并且季鏻配体上的苯环与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。 |
| 英文摘要: |
| The [n-PentylPh3P]2[Mo6O19] polyoxometallate compound was synthesized by the reaction of n-PentylPh3PI and (NH4)6Mo7O24.7H2O at ambient condition. This compound was characterized by single crystal X-ray diffraction, UV-vis, IR spectrum, TGA and electrochemistry (CV). Interestingly, the polyoxometallate compound contains two n-PentylPh3P cations, there were hydrogen bonding interactions between terminal oxygen atoms of [Mo6O19]2- anions and phosphonium cations and consequently, one dimensional chain was formed. Three dimensional structures were constructed by the π-π stacking between the phenyl rings of the cationic phosphonium. Additionally, the photocatalytic property for the degradation of methylene blue (MB) has been investigated. |
