To
prepare new phosphorescent iridium(III) emitters, 2-phenyl-6-(1-phenyl-1-(pyridin-2-yl)ethyl)pyridine
(H2L) has been designed and its reactions with [Ir(μ-Cl)(η4-COD)]2 (1, COD = 1,5-cyclooctadiene)
have been studied. The products obtained depend on the refluxing temperature
of the solvent. Thus, complexes Ir(κ4-C,C′,N,N′-L)Cl(CO) (2), [Ir(η4-COD)(κ2-N,N′-H2L)][IrCl2(η4-COD)] (3), and [Ir(μ-Cl)(κ4-C,C′,N,N′-L)]2 (4) have been formed in 2-ethoxyethanol, propan-2-ol, and 1-phenylethanol,
respectively. Complex 4 reacts with K(acac) to give the
acetylacetonate derivative Ir(κ4-C,C′,N,N′-L)(acac) (5). Complexes 2 and 5 are efficient blue-green and green emitters of classes [6tt+1m+2m]
and [6tt+3b], respectively. They display lifetimes in the range of
1.1–4.5 μs and high quantum yields (0.54–0.87)
in both PMMA films and 2-MeTHF at room temperature.
