Synergistic p-Doping of Polymer-Wrapped Small-Diameter Single-Walled Carbon Nanotubes by Tris(pentafluorophenyl)borane.

ABSTRACT: Despite its comparatively low electron affinity, tris(pentafluorophenyl)borane (BCF) has been widely explored as an efficient molecular p-dopant for semiconducting polymers through the formation of Brønsted acidic complexes as well as its high affinity toward Lewis-basic nitrogen moieties. Many conjugated polymers that are used for selective wrapping and dispersion of semiconducting single-walled carbon nanotubes (SWCNTs) such as poly[(9,9-di-n-octylfluorenyl-2,7-diyl)-alt-(6,6'-(2,2'-bipyridine))] (PFO-BPy) contain nitrogen moieties that should promote interaction with BCF. Here, we demonstrate that BCF indeed efficiently p-dopes even small-diameter (6,5) SWCNTs that are wrapped with large-bandgap PFO-BPy as corroborated by bleaching of the main absorption peaks and the appe
