In the present work, we conducted an investigation on the electrochemical and ECL behavior of Ru(bpy) $\rm{ {_{3}^{2+}}}$ /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) $\rm{ {_{3}^{2+}}}$ /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.
