Photoinduced electron transfer of double-bridged phthalocyanine-fullerene dyads

Three new double-bridged phthalocyanine-fullerene dyads were studied with spectroscopic and electrochemical methods. Photoinduced electron transfer (ET) of the dyads was found to occur both in polar and non-polar environment. Examination of ET energetics revealed that the phthalocyanine-fullerene dyads exist mainly in an extended conformation as opposed to a face-to-face orientation.
