Two europium complexes {Eu·dbm·carb·phen = tris[1-{[6-(9H-carbazol-9-yl)hexoxy]phenyl}-3-{[6-(9H-carbazol-9-yl)-hexoxy] phenyl}propane-1,3-dione](1,10-phenanthroline)-europium(III), Eu·dbm·carb·bath = tris[1-{[6-(9H-carbazol-9-yl)hexoxy] phenyl}-3-{[6-(9H-carbazol-9-yl)hexoxy]phenyl}-propane-1,3-dione] (bathophenanthroline)europium(III)} and their reference compounds were synthesized and characterized. Each complex contains three different chromophores: carbazole (carb), phenanthroline (phen) (or bathophenanthroline, bath) and dibenzoylmethane (dbm) units. The luminescence properties investigated in dichlorometh-ane solution and in solid matrix show that the carbazole moiety is a better sensitizer for the metal-centred emitting states of the Eu III ion compared to the dibenzoylmethane and phenanthroline units. Furthermore, the charge-transporting properties of the carbazole moieties appear to be appealing when integrated into the emitting units. Finally, the high number of appended carbazole units confers a strong light-harvesting character to the structure. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
