| Abstract: | The solution-fluorescence quenching mechanisms of poly (methylcyclohexylsilane), poly (methylphenethylsilane), poly (methylcyclohexylsilane-co-methylphenethylsilane) and poly (methylphenylsilane) are studied by means of steady-state fluorescence, time-resolved fluorescence and UV absorption. The results show that the fluorescence quenching for polysilanes by carbon tetrachloride is the static quenching with energy migration, which is also supported by the qualitative results of the fluorescence quenching behaviors of polysilane by nitromethane (CH3NO2) and 2, 4, 7-trinitrofluorenone (TNF). Synopsis of the first author Hu Huiping, Doctoral student, born on Dec. 15, 1969, engaged in Applied Chemistry. |
