Abstract

A series of oligofluorenes was synthesized and used as a SWNT selecting template to study the chain length effect on SWNTs dispersions in toluene. The octamer exhibits the same selectivity as the corresponding polymer. Nevertheless, SWNT/oligomer complexes are unstable, which allows fast exchange of the oligomer with a coating polymer.
