Abstract

Pyridine-boryl (py-boryl) radicals serve as efficient electron-doping reagents for single-walled carbon nanotubes (SWCNTs). The doping mechanism comprises electron transfer from the py-boryl radical to the SWCNT. The formation of a stable py-boryl cation is essential for efficient doping; the captodative effect of the py-boryl cation is important to this process.

摘要

吡啶硼基（py - 硼基）自由基可作为单壁碳纳米管（SWCNT）的有效电子掺杂试剂。掺杂机制包括电子从py - 硼基自由基转移到SWCNT。稳定的py - 硼基阳离子的形成对于有效掺杂至关重要；py - 硼基阳离子的推拉电子效应在此过程中很重要。
