Abstract

Abstract : A luminescent tetraarylethylene Re(i ) bioprobe exhibits enhanced emission upon site II-specific binding to human serum albumin. Abstract : The synthesis and photophysical properties of luminescent Re(i ) tricarbonyl complexes prepared from bis(pyridyl)- and bis(quinolyl) tetraarylethylene (TAE) ligands are reported. Emission wavelengths of the complexes are influenced by structural variation in the tetraarylethylene ligands, and several complexes display aggregation-induced enhanced emission in aqueous solution. A Re(i ) complex prepared from an indole-functionalized TAE ligand shows significant enhancement in its luminescence intensity accompanied by a remarkable blue shift (∼95 nm) upon specific binding to site II of human serum albumin.
