12-钨磷酸/结晶紫超分子化合物的合成及性质

Synthesis and Characterization of 12-Tungstophosphoric with Crystal Violet Supermolecular Compound

用碱性染料结晶紫和 12 -钨磷酸为原料合成了新型超分子化合物 ,经元素分析和热失重分析确定其组成为C2 5H30 N3· H3PW1 2 O4 0 · 16 H2 O;用 IR、UV、TG- DTA、X射线粉末衍射分析等手段研究了化合物的结构和性质。结果表明 :有机配体与杂多阴离子以氢键形式相结合 ,杂多阴离子仍保持 Keggin结构 。

A new heteropoly supermolecular compound formulated C 25 H 30 N 3·H 3PW 12 O 40 ·16H 2O was synthesized and characterized by elemental analysis?IR?UV?TG DTA and X ray.The results showed that crystal violet do not coordinate with 12 tungstophosphoric,but with proton in heteropolyion by hydrogen bond .Besides,the photochromic properties and thermal stability of title compound was discussed.
