Photophysical properties of composite film of dendron-appended porphyrin and fullerene[60]

Dendron-appended porphyrin (den-por) and C60 (den-C60) were synthesized for the application of photovoltaic materials. The composite films of den-por and den-C60 were subjected to absorption and photoluminescence spectroscopic measurements. We determined that solid-state film, spin-coated with a blend of den-por and den-C60 at weight ratio 1:0.5, showed an efficient photoluminescence quenching via donor-to-acceptor electron transfer.
