摘要

Despite the extraordinary electronic and mechanical properties of single-walled nanotubes (SWNTs), this most remarkable material has not yet entered the realm of industrial applications due to its polydispersity.[1] As-produced SWNTs contain a vast mixture of diameters and chiralities defining their electronic structure as being metallic or semiconducting.[ 2, 3] Furthermore, the strong intertube van der Waals interactions of 500 eVmm1,[4] which render nanotubes virtually insoluble in common organic solvents and water,constrict any application. Among the efforts to increase the processability of this unique material, noncovalent functionalization of these systems represents a corner stone, as it is nondestructive; that is, it does not alter the intrinsic properties of nanotubes.[5–10] Furthermore, it has opened the door towards the development of efficient SWNT separation and sorting techniques.[11]
