Polyacylation of Single‐Walled Nanotubes under Friedel–Crafts Conditions: An Efficient Method for Functionalizing, Purifying, Decorating, and Linking Carbon Allotropes

Abstract

A new way of purifying and separating single-walled nanotubes (SWNTs, see figure) comes in the form of an efficient polyacylation using Friedel–Crafts catalysts in either nitrobenzene as a solvent or in a NaCl/AlCl3 melt. The report method provides a way for the efficient insertion not only of normal acyl chains but also of perfluorinated acyl residues or for crosslinking possibilities by using α,ω-diacyl dichlorides.
