Amido(thio)urea based rhenium (I) tricarbonyl complexes containing various diimine and 1,10-phenanthroline moieties have been synthesized. These amido(thio)urea ligands were incorporated in both mononuclear and binuclear rhenium (I) tricarbonyl complexes. Such complexes have been shown to have rich luminescent properties. They have also been shown to exhibit various fluorescence quenching and/or enhancement upon molecular guest-host interactions, especially in anion sensing. The effects of various electron withdrawing and electron donating groups on the diimine ligands were investigated using both IR and NMR. Luminescence anion sensing studies of these complexes using spectrofluorometric titrations as well as their catalytic studies using cyclic voltammetry will be presented.
