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

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).
