Abstract

Electrochemiluminescence (ECL) of a series of ruthenium(II) diimine complexes with appended crown ethers derived from 1,10-phenanthroline was studied via either the annihilation route or the coreactant schemes, and the ECL efficiency has been determined. The effect of an FSN surfactant on the ECL properties was also studied in buffer solutions. The effect of cation binding on the ECL behavior was examined. The ECL intensity of Ru(bpy)2(phen-2NH)2 has been found to be strongly enhanced upon binding with Zn2+ and alkaline-earth metal ions. The X-ray crystal structure of Ru(bpy)2(phen-2NH)2 has also been determined.

摘要

通过湮灭途径或共反应剂方案研究了一系列带有源自1,10-菲咯啉的冠醚的钌（II）二亚胺配合物的电化学发光（ECL），并测定了ECL效率。还在缓冲溶液中研究了FSN表面活性剂对ECL性质的影响。研究了阳离子结合对ECL行为的影响。已发现Ru(bpy)2(phen-2NH)2与Zn2+和碱土金属离子结合后，其ECL强度会显著增强。还测定了Ru(bpy)2(phen-2NH)2的X射线晶体结构。
