From the first synthesis of rare-earth /9-diketonates in 1897 by Urbain until now, hundreds of different complexes formed by reaction between Lnni ions and /3-diketone derivatives have been described in the literature. Interest for this type of complexes comes from then-potential application in numerous and diverse domains. These complexes can be used for example as extractants in solvent-solvent extraction processes or as active compounds for the development of chelate lasers or liquid lasers. But they can also find applications in NMR as shift reagents or as electroluminescent materials in organic light-emitting diodes (OLEDs) (Binnemans, 2005b).

Abstract The aim of this chapter is to give an in-depth analysis of transition metal complexes that are useful in conversion of solar energy into electricity, and in organic light emitting diodes. In the first part we discuss the historical background of sensitization...

Diketonates are used as model systems for syntheses and calculations because of their similarity to the active sites of metaUoproteins, where metal ions are coordinated to nitrogen, oxygen and sulfur atoms of amino acid residues . Heavy metal complexes are efficient phosphors in organic light-emitting diodes (OLEDs) and have attracted much...
