Luminescent lanthanide complexes are gaining an increasing amount of interest for their applications in various fields such as OLEDs, immunoassays, analytical sensors, and optical communication. They are promising candidates as light-emitting materials in OLEDs to overcome the difficulty of obtaining pure emission colors with conjugated polymers or small organic molecules. N,N-di(pyridin-2-yl)quinolin-8-amine, a novel blue-emitting ligand, was synthesized to coordinate to europium(III). Experimental studies led to insights of its reactivity with europium acetylacetonate complexes. A new Eu(III) complex based on the diazafluorene ligand was synthesized. A sharp emission band was observed, demonstrating that the Eu(III) ion was effectively sensitized by the intramolecular energy transfer of the ligand. Sensitization of europium(III) by the 3MLCT energy based on an iridium complex-ligand in a d-f bimetallic assembly was previously found to emit red light when irradiated with sunlight. 1-(quinolin-8-yl)butane-1,3-dione, a novel bridging ligand, was synthesized to prepare Eu-Ir complexes with potentially enhanced efficiencies.
