Abstract

The energy transfer mechanism between cationic conjugated polyelectrolytes and a single stranded DNA labeled with fluorescein was investigated in terms of Förster resonance energy transfer (FRET) and photo-induced charge transfer (PCT) by time-resolved fluorescence. Both FRET and PCT rate efficiencies were obtained by phenomenological coupled rate equations, which are in excellent agreement with experiments. We found the total energy transfer in the complex is maximized as a consequence of FRET and PCT at an optimum distance 32.7Å.
