Functionalized Arylacetylene Oligomers for Organic Thin‐Film Transistors (OTFTs)

Abstract

Oligo(arylacetylene)-based organic thin-film transistors (OTFTs) possess good structural order and smooth film morphologies, and exhibit field-effect mobilities of 0.3 cm2 V–1 s–1, one of the highest field-effect mobilities reported for an OTFT device that does not possess a self-assembled-layer configuration. The Figure shows the measured output characteristics (drain–source current, IDS versus drain–source voltage, VDS) at different gate voltages (VG).
