摘要： Embodiments herein describe a composition including at least one water-soluble complex having a water-soluble separation agent including a planar portion, at least one pi electron on the planar portion and at least one electron withdrawing group; and a semiconducting single-walled carbon nanotube in an aqueous solution. Further embodiments describe a method of separating metallic single-walled carbon nanotubes and semiconducting single-walled carbon nanotubes including providing carbon nanotubes having an admixture of semiconducting single-walled carbon nanotubes and metallic single-walled carbon nanotubes; and combining the admixture with a water-soluble separation agent in an aqueous solution to form a mixture, in which the water-soluble separation agent includes a planar portion, at least one pi electron on the planar portion and at least one electron withdrawing group.
