Title: Electron Transport with Mobility, μ > 86 cm 2 /(V s), in a 74 nm Long Polyfluorene

Abstract

The mobility of charges on conjugated polymers is a fundamentally important feature of these materials, but most fall far short of transport that might lead one to call them “molecular wires”. A commonly identified bottleneck is flexible dihedral angles between repeat units. Here we find a very high mobility, μ > 86 cm 2/(V s), for electrons attached to polyfluorene polymers in isooctane, despite the presence of varied dihedral angles. In conclusion, the present data suggest that interactions with the surrounding medium may be a principal determinant of charge mobility.
