Chemical Communications, 2012•pubs.rsc.org… In the darkroom, at the working electrode, we observed a bright yellow emission for 1 and
2, and an intense green emission for 3 and 4. We can confirm that the light observed
electrochemically viaECL is the same light detected through PL using an external light
source. … In summary, this ECL study determined that these iridium(III) complexes are
bright ECL luminophores. ECL efficiency is enhanced, compared to [Ru(bpy) 3 ](PF 6 ) 2 ,
when BPO is used as a coreactant. …

Electrochemiluminescence (ECL) of four bright iridium(III) complexes containing aryltriazole cyclometallated ligands is reported. The ECL mechanisms, spectra and high efficiencies via annihilation and coreactant paths have been investigated.
