The thesis focuses on synthesis of lanthanide complexes with the general formula [LnIII(diketonate)3(bipyridine)]. I have prepared twelve products by using two different lanthanides, three different diketones and two different bipyridine ligands, wherein seven compounds are new and five are already known. I have characterized the complexes mainly with NMR and X-ray crystallography. Lanthanide complexes also show typical light emission. I studied this phenomenon with the methods of UV-VIS and fluorescence measurement.
