The complexes Rh(III)(phpy)(2)(EuO) with phpy(-) = deprotonated 2-phenylpyridine and EuO(-) = bidentate anions of the biologically important compounds EuO (troH = tropolone, flaH = flavonol and lumH = lumichrome) have been prepared and characterized with regard to their optical properties. The Rh(III)(phpy)(2) fragment is a useful probe for the emission behavior of these complexes since the phpy IL triplet can serve as a marker. Only the IL states of tp(-) and lum(-) are located below the phpy IL states. While Rh(III)(phpy)(2)(fla) is quite remarkable because it shows an IL (fla) fluorescence, Rh(III)(phpy)(2)(lum) displays an IL (lum) phosphorescence as expected owing to the heavy-atom effect.
