Synthesis, photoluminescence and electrochemiluminescence of ruthenium(II) polypyridyl complexes based on bipyridine derivatives with carbazole moieties

► Carbazole moiety enhances the photoluminescence intensity. ► Carbazole moiety increases the electrochemiluminescence property. ► Complexes with PF6 anions exhibit better electroluminescence than that with Cl−.
