Abstract

Polymer nanowires based on two diketopyrrolopyrrole conjugated polymers with similar chemical structures are shown to have distinct "edge-on" and "face-on" configurations in addition to high well-balanced hole and electron mobilities of 5.47 and 5.33 cm(2) V(-1) s(-1) in field-effect transistors.

Keywords: field-effect transistors; microstructure; organic electronics; polymer nanowires.
