本研究合成了一种疏水性的共反应剂N,N,N',N'-四丙基-戊二胺( TPPD),并将TPPD和疏水型的钌配合物[Ru(bpy)3][4-(Clph)4B]2同时固定在氧化铟锡(ITO)电极表面,构建了一种固相电致化学发光( ECL)传感器。由于TPPD的疏水性,使得它在水相溶液中不容易从ITO电极表面脱落,因此增强了ECL电极的稳定性。该修饰ITO电极显示出较强的、稳定的ECL信号,0.1 mmol/L苯酚对此电极的ECL信号的的猝灭效率达到95.4%,表明其在检测环境中苯酚类化合物的潜在应用价值。还考察了TPPD/[Ru(bpy)3][4-(Clph)4B]2修饰的ITO电极电致化学发光的暂态反应,发现其暂态下的发光寿命明显长于传统TPA溶液体系。

A new organic-soluble co-reactant of N,N,N’,N’-tetrakis(propyl)-pentanediamine (TPPD) was synthesized and co-immobilized with tris ( 2, 2’-bipyridine ) ruthenium ditetrakis ( 4-chlorophenyl ) borate ([Ru(bpy)3][4-(Clph)4B]2) on an indium tin oxide (ITO) electrode for electrochemiluminescent (ECL) study. The hydrophobicity of TPPD prevented its leakage from the electrode surface, thus the long-term stability of the ECL electrode was enhanced. The TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode exhibited strong, stable and reproducible ECL signal. The ECL signal could be quenched efficiently by phenol with a quenching efficiency of 95. 4% in the presence of 0. 1 mmol/L phenol, demonstrating the potential of the modified electrode in determination of phenolic compounds. The transient-state of the electrogenerated chemiluminescence reaction was also investigated, which revealed that the TPPD/[Ru(bpy)3][4-(Clph)4B]2 modified-ITO electrode had a longer lifetime than conventional TPA-Ru(bpy)2+3 co-reactant system.
