摘要: As-produced single-walled carbon nanotubes (SWNTs) are mostly metallic and semiconducting mixtures. The population of SWNTs in the as-produced mixtures is generally much higher than that their counterparts. Therefore, postproduction separation important to many potential uses nanotubes, especially those demanding electrical conductivity yet lower optical absorption. Because planar aromatic species known have somewhat different interactions with SWNTs, this work a molecule pair moieties was specifically designed synthesized exaggerate difference its noncovalent functionalization solubilization two types nanotubes. As demonstrated, exhibited significant selectivity toward allow convenient harvesting bulk fractions high purities. results s...
