Abstract

This thesis mainly describes the synthesis of functionalised Re(CO)3+ units with polypyridine ligands and their characterization by spectroscopic and X-ray crystallographic methods. Chapter 1 includes general introduction of rhenium and its carbonyl compounds, their preparation, substitution of carbonyls in general organometallic compounds and in rhenium carbonyl compounds. This chapter also describes the photophysical and redox active properties of rhenium. There have been numerous reports that have used the Re(bpy)(CO)3Cl moiety as building blocks for supramolecular species, sub-units of photodevices or even as potential biological labels. Chapter 2 and 3 describe the investigation of new potential complexes where the bipyridyl ligand has been replaced by a ligand which offers greater possibilities in functionalisation. These include Re(I)-complexes containing 2,2' 6',2'-terpyridine and 2,2, 6',2':6',2''-quaterpyridine ligands. A number of novel rhenium compounds have been synthesized and their coordinative and spectroscopic properties have been elucidated. The complexes also characterized by X-ray crystallographic studies. In chapter 4, a number of Re(bpy)(CO)3+ complexes containing thiourea, pyridyl terpyridine and 1-methyl-4-pyridyltetrahydropyridine ligands have been prepared and their anion binding, cation binding and redox active properties have been described. The rhenium compound of 1-methyl-4-pyridyltetrahydropyridine may prove to be useful molecular probe for the biochemical research into the origin of Parkinsons-like conditions. This chapter also dealt with the synthesis of water soluble Re(bpy)(CO)3+ analogues using disodium bathophenanthroline sulphonate ligand.
