本文通过超声反应,将氮杂15-冠-5-苯乙炔引入聚苯乙烯负载多吡啶铂(Ⅱ)配合物.研究发现聚苯乙烯负载氮杂15-冠-5-苯乙炔基多吡啶铂(Ⅱ)配合物完全保持了单体多吡啶铂(Ⅱ)配合物的性质,并能够通过发光光谱的显著增强选择性地检测Mg^2+离子.通过加入极性溶剂沉淀析出聚苯乙烯负载多吡啶铂(Ⅱ)配合物,从而达到分离的目的.
N-15-monoazacrown-5-phenylacetylide was introduced to the polystyrene-supported polypyridyl platinum(Ⅱ) complex by ultrasonication in DMF. The obtained polystyrene-supported complex P1 can detect Mg^2 + specifically both in solution color and luminescence intensity similar to that of the unbound mononuclear platinum(Ⅱ) complex M1. Moreover, the polystyrene-supported platinum(Ⅱ) acetylide complex could be separated simply by adding polar solvent for precipitation.
