Abstract

Two phosphorescent cyclometalated iridium(III)-triptycenyl-1,10-phenanthroline complexes Ir(ppy)2(tpt-phen)+ (1) and Ir(bhq)2(tpt-phen)+ (2) {ppy=2-phenylpyridine, bhq=Benzohquinoline, tpt-phen=triptycenyl-1,10-phenanthroline} have been synthesized and structurally characterized. The structure of complex 2 has been studied by single crystal X-ray crystallography. The photophysical properties of complexes in a different solvent have also been investigated. The binding of complexes to the double stranded calf thymus (CT-DNA) has been investigated by spectroscopic techniques. These complexes condense originally circular plasmid DNA into particulate structures. The DNA-condensation induced by these complexes have been investigated by electrophoretic mobilty shift assay, dynamic light scattering, and fluorescence microscopy. Furthermore, the cytotoxicity of these complexes towards HeLa cells have been studied and their cellular localisation properties have been investigated by fluorescence microscopy.
