Selective Suppression of Conductance in Metallic Carbon Nanotubes

摘要

We have demonstrated that electrophilic molecules such as 2,4,6-TPPT and 1,3-BDYT preferentially react with metallic SWNTs through noncovalent and covalent binding, respectively. Although the highest yield at the moment is about ～35%, we believe that the performance can be greatly improved by narrowing down the diameter distribution of nanotubes to 1～2 nm, where strain-related nonspecific reactivity can be lifted.
