β¦ Synopsis
The room-temperature solution flourescence quenching of polysilane copolymers by bromohydrocarbons such as BrCH,CH, and BrCH,CH,Br was studied. The fluorescence quenching data were in conformity to the equation In (F,/F) = NV[Q], and almost linear In (F,/F) u [Q] straight lines were obtained. According to the fluorescence quenching theory, the fluorescence quenching here may be simply the static fluoresce&e quenching.

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 lif
