Synthetically Tailored Excited States: Phosphorescent, Cyclometalated Iridium ACHTUNGTRENNUNG(III) Complexes and Their Applications

Stable and color tunable emission properties based on non-cyclometalated gold(III) complexes.

Stable and emission tunable non-cyclometalated gold(III) triaryl complexes of the type [(L)Au(C6F5)3] [L = 2-(2,4-difluorophenylpyridine) (1), 4-phenylpyridine (2), 2-phenylpyridine (3), 2-phenylisoquinoline (4), 2-thienylpyridine (5)] were synthesized starting from a common precursor complex [(THT)Au(C6F5)3] [THT = tetrahydrothiophene] in good to modest yields. Extensive characterization of th...

Observation of the long-lived triplet excited state of perylenebisimide (PBI) in C^N cyclometalated Ir(III) complexes and application in photocatalytic oxidation.

Perylenebisimide (PBI) was used to prepare C^N cyclometalated Ir(III) complexes that show strong absorption of visible light and it is the first time the long-lived triplet excited state of PBI chromophore was observed in a transition metal complex (τT = 22.3 μs). Previously, the lifetime of the triplet state of PBI in transition metal complexes was usually shorter than 1.0 μs. Long-lived tripl...

"Click" synthesis of heteroleptic tris-cyclometalated iridium(III) complexes: Cu(I) triazolide intermediates as transmetalating reagents.

Efficient synthesis of heteroleptic tris-cyclometalated Ir(III) complexes mer-Ir(C(/\)N)(2)(trpy) (trpy = 2-(1H-[1,2,3]triazol-4-yl)pyridine) is achieved by using the Cu(I)-triazolide intermediates formed in "click" reactions as transmetalating reagents. Ligand preparation and cyclometalation of Ir(III) is accomplished in one pot. The robust nature of click chemistry provides opportunities to i...

Gold(iii)-arene complexes by insertion of olefins into gold-aryl bonds.

The synthesis and characterization of the first gold(iii)-arene complexes are described. Well-defined (P,C)-cyclometalated gold(iii)-aryl complexes were prepared and characterized by NMR spectroscopy. These complexes swiftly and cleanly reacted with norbornene and ethylene to provide cationic gold(iii)-alkyl complexes, in which the remote phenyl ring was η2-coordinated to gold. The interaction ...
