Özet:

 

The energy transfer between coumarin 35 (C35) and pyronin  compounds, which are xanthene derivatives, i.e. pyronin B (PyB) and  pyronin Y (PyY), in methanol was investigated at room temperature by  using steady-state absorption, emission, and time-resolved  fluorescence spectroscopy.  Fluorescence energy transfer rate  constants (kT) and critical radius (R0) were determined for C35-PyB  and C35-PyY molecular pairs in methanol.  The obtained values of kT  and R0 indicated that the dipole-dipole interaction between C35-PyB  and C35-PyY molecular pairs accounted for the energy transfer  mechanism.  The energy transfer efficiency and the distance between  the donor and acceptor (r) were also calculated for donor-acceptor  pairs using Förster's theory.
