Single-walled carbon nanotubes (SWNTs) may be grown from designed seeds containing an SWNT and the catalyst required for continued growth. Dodecyl side-walled functionalized SWNTs (DD-SWNTs) are end-functionalized with 4-hydroxypyridine via dicyclohexylcarbodiimide coupling to allow covalent coordination of an inorganic cluster pro-catalyst (FeMoC). DD-SWNT-py-FeMoC on spin-on glass was exposed to H2/CH4at 800 °C, resulting in 3-fold growth in the length of 40% of the seed SWNTs. Only ∼1% of the procatalyst alone nucleate SWNTs under the same conditions, suggesting effective separation of the nucleation and growth processes.

N,N′-Substituted amines (as illustrated using TMEDA) will react with a short chain 2-alkoxy-2-oxo-1,3,2-dioxaphospholane, to form a stabilised phospholane salt and not the corresponding phosphobetaine as anticipated.
