Cuvette-Based Electrogenerated Chemiluminescence Detection System for the Assessment of Polymerizable Ruthenium Luminophores

Abstract

Herein, we validate a novel cuvette-based approach to measure electrogenerated chemiluminescence (ECL) by employing the hyphenation of a commercial spectrometer and a potentiostat. The new experimental design provides simultaneous acquisition of electrochemical and ECL data, allowing complementary analysis by both techniques. Preliminary analysis of an organometallic ECL standard, tris(2,2′-bipyridine)ruthenium(II) (Ru(bpy)32+), and tripropylamine (TPA), showed excellent reproducibility both in terms of the electrochemistry and the ECL signal. Equally as important, the acquired electrochemistry and ECL from the Ru(bpy)32+/TPA system served as a baseline for evaluating the ECL response of polymerizable ruthenium luminophores.
