基于 [Ru(bpy)3 ]2+ 系统的电化学发光 (ECL) 广泛用于免疫测定。为了扩展基于 ECL 的应用前景，IrIII 配合物由于其优异的发光性能和可调谐的发射波长而作为探针最近引起了人们的关注。在这里，我们描述了一系列使用大 π 共轭配体和不同辅助螯合物的 Ir 配合物。合成的配合物已经过化学和光谱表征，并用于采用湮灭和共反应物方法的 ECL 测量。研究中的一种 IrIII 配合物采用过氧化苯甲酰 (BPO) 共反应物方法，在乙腈中表现出有史以来最亮的 ECL 效率。
Electrochemiluminescence (ECL) based on [Ru(bpy)3 ]2+ systems is widely utilized for immunoassays. In order to extend the promising potential of ECL-based applications, IrIII complexes have recently attracted attention as probes because of their excellent luminescent properties and tunable emission wavelength. Here we describe a series of Ir complexes using a large π-conjugated ligand and different ancillary chelates. The complexes synthesized have been chemically and spectroscopically characterized and used for ECL measurements with annihilation and co-reactant methods. One of the IrIII complexes investigated exhibits the brightest, ever reported, ECL efficiency in acetonitrile employing the benzoyl peroxide (BPO) co-reactant method.
