A series of rhenium complexes with acetylamino- and trifluoroacetylamino-containing 1,10-phenanthroline ligands have been synthesized, characterized and their photophysical and electrochemical properties studied. These complexes were found to show significant UV-vis and emission changes on addition of CN−, F− and AcO− anions. Their reactivity towards CN−, F− and AcO− anions, was also investigated by UV-vis, emission and 1H NMR spectroscopy. The reaction product between the trifluoroacetylamino-containing 1,10-phenanthroline ligand and the CN− anion has also been structurally characterized by X-ray crystallography.
