Electron transfer in a disordered polymeric system: fluorescence spectroscopy study

Experimental studies of electron transfer in a polymeric matrix were made u sing fluorescence spectroscopy. Donor molecules were excited in the presenc e of acceptor molecules and the decay time of the donor fluorescence was me asured. The data were analyzed using the model for electron transfer in a d isordered system. The idea was to verify the validity of the model in the v ery large disorder limit. Using a random sample, the electron transfer rate obtained could be compared to the one obtained considering the random dist ribution of acceptors. A good agreement was obtained.
