合成并表征了一种新型的水溶性含糖铱二亚胺配合物。首次研究了该配合物在水溶液中的电致发光行为，发现其在Pt工作电极上的电致发光信号远高于[Ru（bpy）（3）]（2+）。在铂电极上，在缓冲溶液中，铱（III）配合物的电化学发光测定了三正丙胺（TPA）和抗生素，发现该方法具有良好的灵敏度和重现性。新的铱（III）配合物被发现显示出良好的溶解性在水溶液中和一个强大的电化学发光信号在铂电极上，这可能开辟了其应用于分析的可能性。
A new water-soluble iridium(III) diimine complex with appended sugar was synthesized and characterized. The electrochemiluminescent behavior of the new complex in aqueous buffer was first studied and the ECL signal was found to be much higher than that of [Ru(bpy)(3)](2+) at a Pt working electrode. Tri-n-propylamine (TPA) and antibiotics were determined by the ECL of the iridium(III) complex in aqueous buffer at the Pt electrode and the method was found to show good sensitivity and reproducibility. The new iridium(III) complex was found to display good solubility in aqueous solution and a strong ECL signal at the Pt electrode, which might open up the possibility of its application in analysis.
