The
binding mechanism and polymer–fluorescence probe interactions between
polyethyleneimine (PEI) and Rose Bengal (RB) was investigated by using UV–Vis
absorption, steady- state and time-resolved fluorescence spectroscopy
techniques since they remain major research topics in photophysics. The
spectroscopic data indicated that an unusual interactions for PEI-RB system was
occurred. Binding constants (KSV) and quantities of binding were calculated
with high linearity. Significant photophysical parameters as band shifts,
fluorescence quantum yields and fluorescence lifetimes were determined to
comprehend how photophysical and spectroscopic features of the dye compounds were
affected by the polymer. With this respect, this study is significant in terms
of gaining dye-polymer relationship to the literature.
