Pyrene application as a fluorescent probe for the determination of silver state in a perfluorosulfonic membrane

详细

Features of pyrene fluorescence in a perfluorosulfonic membrane modified by silver confirm the presence of two forms of the metal in it. Fixation of isolated pyrene molecules in the membrane proceeds on planar “near-wall” silver species. The presence of silver nanoparticles in the membrane is detected by the bright fluorescence of pyrene dimers in the absence of luminescence of its separate molecules.
