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

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. Test case: A cuvette‐based electrogenerated chemiluminescence (ECL) detection system is fabricated by utilizing platinized FTO glass (as the working electrode), a potentiostat, and a spectrometer. This system is operationally tested against the known tris(2,2′‐bipyridine)‐ ruthenium(II) (Ru(bpy)32+)/tripropylamine system and then used to asses a polymerizable ruthenium luminophore.
