Significance

A single-walled carbon nanotube (SWCNT) may have a left- or right-handed helical structure (designated M and P by IUPAC nomenclature), in accord with the graphene sheet from which the nanotube was formed. To extend the potential applications and fundamental studies of carbon nanotubes, a method for separating the P and M forms is desired. Chiral bisporphyrins 1 and 2 selectively complex with either (P)- or (M)-SWCNTs and thereby enable preferential extraction of one chiral form.
