Enhanced electrogenerated chemiluminescence of tris(2, 2'-bipyridyl) ruthenium(II)/tripropylamine in the presence of pyridine and its analogues

Abstract

In the present work, we conducted an investigation on the electrochemical and ECL behavior of Ru(bpy)2+3/TPrA system in the presence of pyridine and its analogues on platinum and gold electrode. Results showed that pyridine and its analogues enhanced Ru(bpy)2+3/TPrA ECL signal and exhibited different enhancement effects on different electrodes. On platinum electrode, the maximum enhancement factor of about 5 was obtained. On gold electrode, a low-oxidation-potential (LOP) ECL signal occurred and increased. © 2009 Wiley-VCH Verlag GmbH & Co.
