Electrochemiluminescence quenching of tris(2,2′-bipyridyl)ruthenium

Determination of malachite green in fish based on magnetic molecularly imprinted polymer extraction followed by electrochemiluminescence

“…Based on previous studies [19,42], we knew that trace MG showed efficient quenching over Ru(bpy) 3 2 þ /TPA, the high K sv (1.2 Â 10 5 M À 1 ) implied that the method was sensitive, and the quenching mechanism was also proposed. Resonance energy transfer from excited-state luminophore Ru(bpy) 3 2 þ n to MG and dynamic quenching are suggested as the quenching mechanism.…”

Synthesis, crystal structures, fluorescence, electrochemiluminescent properties, and Hirshfeld surface analysis of four Cu/Mn Schiff‐basecomplexes

“…It is tentatively suggested that the introduction of the Cu and Mn ions, in particular Mn ion, could strengthen the spin-orbit coupling effect and enhance the ECL emission. Compared to Ru-, Ir-, Pt-, Re-, Os-, and Cd-complexes reported previously, [43][44][45] the four complexes as novel polymer ECL materials F I G U R E 9 Cyclic voltammetry curves for 1-4 exhibit better economic benefits and environmental friendliness because copper and manganese are less-toxiclow-priced metals.…”

Determination of Brilliant Blue FCF by a Novel Solid-state ECL Quenching Sensor of Ru(bpy)32+-poly(sulfosalicylic acid)/GCE

“…Actually, more attention has been paid to enhanced ECL, and the investigation of ECL quenching has been limited. 20 Cui et al 21 dopamine, 32 and phenolphthalein. 33 Most analytes involved in the quenched ECL are limited to some specific compounds, i.e.…”

“…20 Until now, most ECL systems have been utilized for detection by coupling with separation techniques, such as flow-injection analysis, 21 capillary electrophoresis, 22 and HPLC. 23,24 In those methods, ECL reagents were generally used as solution-phase.…”
