Sorting and decoration of semiconducting single-walled carbon nanotubes via the quaternization reaction.

ABSTRACT: A study for the selective separation and functionalization of alcohol-soluble semiconducting single-walled carbon nanotubes (sc-SWCNTs) is carried out by polymer main-chain engineering. Introducing tertiary amine groups endows the functionalized sc-SWCNTs with alcohol-soluble properties and introducing the pyrimidine rings allows to increase the selective purity of sc-SWCNTs. In this study, a series of poly[(9,9-dioctylfluorene)-2,7-(9,9-bis(3'-(N,N-dimethylamino)propyl)-fluorene)] _m -alt-[2-methylpyrimidine-2,7-(9,9-dioctylfluorene)] _n (PFPy) are used for the selective dispersion of semiconducting single-walled carbon nanotubes, where n and m are the composition ratio of the copolymer. When m = n, the eff
