Extremely high ECL efficiencies seem to be a common feature of the homoleptic-IrL3 as well as the heteroleptic-L2Ir(X) iridium(III) cyclometallated complexes. Extremely high ECL efficiencies (up to 0.55) were observed via ion annihilation between the electrochemically generated L2Ir(acac)+ or L2Ir(pico) + cations (where... 

The afore-mentioned challenge has been reached with an heteroleptic C N cyclometalated iridium(iii) complex incorporating a monostyryl/ distyryl BODIPY ligand via acetylide bonds of 2,2 -bipyridine, see Fig. 10. This complex shows both absorption and fluorescence emission bands in the near infra-red region (NIR) and exceptionally long-lived triplet excited states (t = 156.5). ...
