Just a brief note, via Slashdot and Technology Review: a Cambridge group has published the synthesis route for a fullerene polymer – 
they call it fullerene-based one-dimensional nanopolymer – which might be an interesting acceptor material for organic photovoltaics. The preprint can be found on arXiv. The fullerene polymer has not been functionalised yet, it is thus not soluble enough for solution processing. Also, the electrical conductivity remains an open question… are the spacers critical? Nevertheless, interesting addition to the group of fullerene derivatives, after the recent bis-fullerenes [Lenes 2008] and endohedral fullerenes [Ross 2009].
