Novel electrogenerated chemiluminescence (ECL) reagents C1 , C2 , and C3 with high fluorescence quantum yields bearing 15‐crown‐5 moiety have been synthesized and characterized. The photophysical, electrochemical, and ECL characters of these compounds have been studied in a 1:1 (v/v) PhH/MeCN mixed solvent. The ECL intensity is enhanced distinctly with the increase in the fluorescence quantum yield. Their ECL behaviors have been studied using annihilation and co‐reactant methods (tri‐ n ‐propylamine (TPrA) was used as a co‐reactant), respectively. The stable ECL emissions of compounds C1 – C3 can be ascribed to the typical and simple monomer ECL emission via S‐route. Copyright © 2008 John Wiley & Sons, Ltd.
