It has been shown that composites of p-conjugated poly-mers and C60have promise for application in photovoltaicdevices, owing to efficient electron transfer from the conju-gated polymer to C60under visible light.[1±3]In this respect,composites of p-conjugated polymers and carbon nano-tubes are of great interest in terms of the novel electronicinteraction between these two elements and the mechani-cal reinforcement of the polymer film. Here, we report on
