title: Hybrids of copolymers of fluorene and C60 -carrying-carbazole with semiconducting single-walled carbon nanotubes.
abstract: Three different copolymers of C60 -carrying-carbazole and fluorene units with different copolymer composition ratios were designed and synthesized. On the basis of photoluminescence, atomic force microscopy, and Vis-NIR and Raman spectroscopic analysis, we found that these copolymers solubilize only semiconducting single-walled carbon nanotubes (sem-SWNTs) to form copolymer/sem-SWNT hybrids, in which energy transfer from the copolymer/C60 moieties to the SWNTs was revealed. By comparing two possible hybrid structures with molecular-mechanics simulations, the greatest stabilization was found when the C60 moieties lay on the sem-SWNT surfaces.
