Abstract
A compound of Formula (0): where Ar is one or more substituted or unsubstituted aromatic units, R is independently H, F, CN, a C-Clinear or branched aliphatic group or a C-Clinear or branched aliphatic acyl group, and n is an integer 3 or greater, is useful for sorting and dispersing carbon nanotubes (CNTs) and for producing printed electronic devices (e.g. COsensors, TFTs) in which the CNTs are functionalized with the compound.
