Design and Synthesis of Blue-Emitting Cyclometalated Iridium(III) Complexes Based on Regioselective Functionalization
A series of tris‐cyclometalated IrIII complexes were prepared by regioselective substitution reactions (formylation, thiocyanation, and iodination) and subsequent conversions (cyanation, cross‐coupling reaction, reduction, and oxidation) on a 2‐(4′‐methoxyphenyl)pyridine (mppy) ligand of fac‐[Ir(mpp...

Summary: | A series of tris‐cyclometalated IrIII complexes were prepared by regioselective substitution reactions (formylation, thiocyanation, and iodination) and subsequent conversions (cyanation, cross‐coupling reaction, reduction, and oxidation) on a 2‐(4′‐methoxyphenyl)pyridine (mppy) ligand of fac‐[Ir(mppy)3]. The introduction of electron‐withdrawing groups such as CHO, CN, and sulfonyl groups (SO2Me, SO2Ar) at the 5′‐position of the phenyl ring of the mppy portion induces a considerable blueshift in luminescence emission (from 495 nm to approximately 465 nm) in degassed organic solvents.
Blue‐emitting fac‐[Ir(mppy)3] [mppy = 2‐(4′‐methoxyphenyl)pyridine] derivatives have been prepared by regioselective substitution reactions and subsequent conversions. The introduction of electron‐withdrawing groups such as CHO, CN, andsulfonyl groups (SO2Me, SO2Ar) at the 5′‐position of the mppy portion induces a considerable blueshift of luminescence emission in organic solvents. |
