Most approaches to the chemical separation of sem-/met-SWNTs are based on small neutral molecules or conjugated aromatic polymers, which characteristically have low separation/dispersion efficiencies or present difficulties in the postseparation removal of the polymer so that the resulting field-effect transistors (FETs) have poor performance.
