Functionalization of Single-Wall Carbon Nanotubes by Tandem High-Pressure/Cr(CO)6 Activation of Diels−Alder Cycloaddition

Abstract
An original method to induce Diels-Alder cycloadditions on carbon nanotubes is reported. The process is based on the double activation of the nanotube surface by combining high pressure and Cr(CO)6. This allows the efficient functionalization of carbon nanotubes by electron-rich dienes.
