Modulation of Ligand Fluorescence by the Pt(II)/Pt(IV) Redox Couple.

ABSTRACT: The dangling carboxylic acid moiety of the known platinum(II) complex, [Pt(edma)Cl(2)] (edma = ethylenediaminemonoacetic acid), was functionalized via amide coupling chemistry with benzyl amine and dansyl ethylenediamine to afford the derivatives [Pt(edBz)Cl(2)] (1) and [Pt(edDs)Cl(2)] (2). Subsequent oxidation of these platinum(II) complexes with iodobenzene dichloride in DMF yielded the respective platinum(IV) analogues, [Pt(edBz)Cl(4)] (3) and [Pt(edDs)Cl(4)] (4). All four platinum complexes were characterized by multinuclear NMR spectroscopy, IR spectroscopy, electrospray ionization mass spectrometry, and elemental analysis. In addition, compounds 1 and 3 were structurally characterized by X-ray crystallography. The photophysical properties of the compounds bearing the fluorescent dans
