Abstract:

We demonstrate a strategy for p-type doping of carbon nanotubes (CNTs) by enhancing their autoxidation in air using lithium bis(trifluoromethylsulfonyl)imide (Li:TFSI). The salt promotes oxygen-mediated electron withdrawal without acting as an oxidant itself. This approach produces air-stable, highly conductive CNTs without aggressive oxidants, offering a robust route for molecular electronics.

Radical Autoxidation

3.3K

The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...
