A newly designed ruthenium(II) complex (Ru-Se) bearing a selone moiety showed unexpected enhancement in low-oxidation-potential (LOP) electrochemiluminescence (ECL) observed at electrode potentials before the oxidation of Ru-Se in the presence of tri-n-propylamine (TPrA), which was primarily attributed to the heavy atom effect caused by the selone in Ru-Se.

•We synthesized a newly designed ruthenium(II) complex (Ru-Se) containing a selone moiety.•Low-oxidation-potential ECL of Ru-Se was enhanced compared to that of Ru(bpy)32+ in the presence of tri-n-propylamine.•The enhanced LOP ECL of Ru-Se was attributed to the heavy atom effect induced by the selone moiety.
