Zusammenfassung
The complex Ir-III(phpy)(2)(naIa) with phpyH=2-phenylpyridine and nalaH=3-(2-naphthyl)alanine was prepared and characterized. The electronic spectrum of the complex shows long-wavelength absorptions which are attributed to the Ir-III(phpy)(2) Chromophore. The lowest-energy excited state is a metal-to-ligand charge transfer (MLCT) triplet which is emissive under ambient conditions. Excitation of ...

The complex Ir-III(phpy)(2)(naIa) with phpyH=2-phenylpyridine and nalaH=3-(2-naphthyl)alanine was prepared and characterized. The electronic spectrum of the complex shows long-wavelength absorptions which are attributed to the Ir-III(phpy)(2) Chromophore. The lowest-energy excited state is a metal-to-ligand charge transfer (MLCT) triplet which is emissive under ambient conditions. Excitation of the naphthyl chromophore at shorter wavelength is followed by an efficient energy transfer to the Ir-III(phpy)(2) fragment. (C) 2004 Elsevier B.V. All rights reserved.
