Novel polymer nanowire crystals of diketopyrrolopyrrole-based copolymer with excellent charge transport properties

Adv Mater. 2013 Aug 14;25(30):4102-6. doi: 10.1002/adma.201301536. Epub 2013 Jun 19.

Abstract

The first demonstration of polymer nanowire (PNW) crystals based on a diketopyrrolopyrrole-based copolymer (i.e., PDTTDPP), and their application to field-effect transistors (FETs) is reported. Remarkably, transmission electron microscopy and selected area electron diffraction analyses of the PNW reveal its single-crystalline (SC) nature. FETs fabricated of a SC PNW exhibit a maximal charge carrier mobility of ≈7.00 cm(2) V(-1) s(-1) , which is almost one order of magnitude higher than that of the thin-film transistors made of the same polymer (PDTTDPP).

Keywords: conjugated copolymers; diketopyrrolopyrrole; field-effect transistors; polymer nanowires; single crystalline.
