Abstract

Summary: Soluble carbon nanotubes were prepared by treating SWNTs with sec‐butyllithium and subsequently using the generated carbanions as the initiator to graft P__t__BA and P__t__BA‐b‐PMMA onto the surface of SWNTs. The anionic polymerization initiated by SWNTs‐bearing carbanions not only provides a powerful strategy for functionalizing SWNTs but also gives us knowledge of the sidewall chemistry of SWNTs. The results indicate that a carbanion born on SWNTs behaves like an anionic initiator with high steric hindrance.
