Abstract: Abstract Five novel cationic cyclometalated Ir(III) complexes of type [(CˆC)IrX(PPh3)2(dmbpy)]A (X = halogen; dmbpy = 4,4′-dimethoxy-2,2′-bipyridine; A = counterion) were synthesised and characterised. Complexes 1–3 ([(CˆC)IrCl(PPh3)2(dmbpy)]A) have different anions (A = Cl−, CF3SO3−, PF6−) and complexes 4–5 ([(CˆC)IrX(PPh3)2(dmbpy)]PF6) have different halogen ligands (X = Br−,… read more here.
