The classic and most widely used co-reactant electrochemiluminescence (ECL) reaction of tris(2,2'-bipyridine)ruthenium(ii) ([Ru(bpy)]) and tri--propylamine is enhanced by an order of magnitude by -[Ir(sppy)] (where sppy = 5'-sulfo-2-phenylpyridinato- ,), through a novel 'redox mediator' pathway. Moreover, the concomitant green emission of [Ir(sppy)]* enables internal standardisation of the co-reactant ECL of [Ru(bpy)]. This can be applied using a digital camera as the photodetector by exploiting the ratio of R and B values of the RGB colour data, providing superior sensitivity and precision for the development of low-cost, portable ECL-based analytical devices.
三（2,2'-联吡啶）钌（II）（[Ru(bpy)]）与三丙胺的经典且应用最广泛的共反应物电化学发光（ECL）反应通过-[Ir(sppy)]（其中sppy = 5'-磺基-2-苯基吡啶酸根-，）经由一种新型的“氧化还原介质”途径增强了一个数量级。此外，[Ir(sppy)]*伴随的绿色发射使得[Ru(bpy)]的共反应物ECL能够进行内标定量。通过利用RGB颜色数据的R值和B值之比，这可以使用数码相机作为光电探测器来应用，为开发低成本、便携式基于ECL的分析设备提供了卓越的灵敏度和精度。
