Protein binding studies of luminescent rhenium(I) diimine complexes

► The work presented in this manuscript involves the binding studies of Re(I) complexes (1a-2b), with bovine serum albumin. ► This is the first report on the binding of these Re(I) complexes with bovine serum albumin. ► These Re(I) complexes can be used as class of probe for biophysical studies of macromolecules.
