چکیده انگلیسی
Fluorescein and rhodamine linked porphyrin dyads were synthesized as new intramolecule electron transfer systems. The UV–vis spectra, fluorescence spectra and lifetime were measured. It is found that in the model systems fluorescence spectra of fluorescein and rhodamine are effectively quenched and the fluorescene lifetime of porphyrin section decreased. Fluorescence lifetime of rhodamine porphyrin dyads decreased more effectively showing that there are effective electronic interactions between the two subunits. We can conclude that electron and energy transfers to porphyrin section through fluorescence emission in fluorescein porphyrin dyads or through space in rhodamine porphyrin dyads.
