Quenching of pyrene fluorescence by cupric ions in micellar solution: effect of quenching on the polarity reported by the probe
1988
Abstract The ratio of peak III to peak I intensities of the so-called III and I fluorescence bands of pyrene increases dramatically when cupric ions are used as quenchers for pyrene emission in sodium dodecyl sulfate micelles. These results indicate a decrease in the polarity sensed by the probe when its lifetime is reduced and are attributed to the interdependence of kinetic and spectroscopic parameters.
