The platinum compounds are now of a great interest for catalysis, photovoltaics, medical applications. In particular, cyclometalated compounds of Ir(III) and Ru(II) could be used as photosensibilizers in Grätzel solar cells due to their high stability and high extinction coefficient.
Our research is devoted to the study of how the structure of ligands affects electrochemical properties of resulting cyclometalated compounds.
We synthesize the complexes with bidentate C- and N-donor ligands, e.g. 2-arylbenzimidazoles and phenanthroimidazoles. The complexes are analysed by means of XRD, NMR-, IR-, mass-spectrometry, luminescent spectrometry.
