While rhenium diimine tricarbonyl complexes are well known, the ability to tune the luminescent behavior by the addition of electron withdrawing or donating groups on a phenanthroline ligand has not yet been shown. As luminescence has applications in bioimaging and dye-sensitized solar cells, developing complexes with varied luminescent behavior is important. In this work, we have synthesized a library of rhenium tricarbonyl complexes with functionalized phenanthroline ligands (Re(CO)3(diX-1,10-phenanthroline)Cl where X=Cl, CCl3, CBr3, OH, OCH3, CH3, SO3H , NH2). Since the 3MCLT is the source of luminescence in these complexes, small changes in the electron withdrawing capacity of the ligand alters the luminescence observed. In addition, pH sensitive ligands such as 4,7-dihydroxyl-1,10-phenanthroline, 4,7-diamino-1,10-phenanthroline, 1,10-phenanthroline-4,7-dicarboxylic acid, and 1,10-phenanthroline-4,7-disulfonic acid have shown to impart complexes with pH dependent luminescent behavior.
