Dowling, Sally D.; Mullin, Jerry L.; Seitz, W. Rudolf published the artcile< Binding of sulfonated fluorophors by metal-polyethylenimine complexes>, Computed Properties of 112-63-0, the main research area is pyrenesulfonate binding polyethylenimine metal complex; anilinonaphthalenesufonate binding polyethylenimine metal complex; copper polyethylenimine complex binding sulfonate; zinc polyethylenimine complex binding sulfonate; silver polyethylenimine complex binding sulfonate; fluorescence polyethylenimine complex binding sulfonate.
The binding of Na 1-pyrenesulfonate (I) [59323-54-5], tetra-Na 1,3,6,8-pyrenetetrasulfonate (II) [59572-10-0] and magnesium 1,8-anilinonaphthalenesulfonate (III) [18108-68-4] to the Cu(II), Zn(II), and Ag(I) complexes of poly(ethylenimine) (IV) was studied by measuring fluorescence intensities and excitation and emission spectra at various metal-to-pyrene ratios in the presence of IV. I reacts to form ground-state dimers when bound to Cu(II)- and Zn(II)-IV: on Cu(II)- and Zn(II)-IV and to a lesser extent on Ag(I)-IV the amounts of bound I exceed that required for electroneutrality under certain conditions: II binds more strongly to Ag(I)-IV than to Cu(II)-IV. I forms excimers to only a very small extent when bound to protonated IV. III emits at shorter wavelength when bound to Zn(II)-IV than when bound to protonated IV. The results are interpreted as indicating that binding to Cu(II)- and Zn(II)-IV is predominantly hydrophobic and territorial because the IV shields the bound counterion from the charge on the metal ion. On Ag(I)-IV and particularly on protonated IV the charge on the polyelectrolyte is more acceptable to bound counterions, causing electrostatic interactions to be more important and binding to be more site specific.
