Abstract
The interaction of tetrabramofluorescein (TBF) and DNA was studied by the fluorescence and SS-RTP. The effect of the ion strength and ethanol on the fluorescence spectra of TBF in the presence of DNA and absence of DNA was investigated. In addition, the effect of pH on the SS-RTP spectra of TBF was also examined. The quenched constant was 719.74 and 880.22 in the absence and presence of DNA respectively. Finally, the interaction mode between TBF and DNA was discussed from the fluorescence quenched and phosphorescence polarized experiments.
