A novel luminescent Zn2+ ions chemosensor, a cyclometalated platinum(II) bipyridyl acetylide complex, was designed. Of particular significance is that it shows a high sensitivity towards Zn2+ ions without interference from other biologically important cations in acetonitrile. The tautomerization of amide favors detecting Zn2+ ions among other HTM (heavy and transition metal) ions in aqueous systems
设计了一种新型的发光Zn 2+离子化学传感器,一种环金属化的铂(II)联吡啶基乙炔化物络合物。特别重要的是,它对Zn 2+离子显示出高灵敏度,而不受来自其他生物学上重要的阳离子的干扰。乙腈。酰胺的互变异构有助于检测水体系中其他HTM(重金属和过渡金属)离子中的Zn 2+离子。
