Abstract

Thienoacene-based π-conjugated oligomers, DTT-NP8 and DTT-BT8, were designed and synthesized. Their strong intermolecular interactions originating from S⋯S contacts enable the fabrication of single-crystal microribbons via solution processing. Organic single-crystal transistors exhibited field-effect mobilities as high as 0.54 cm²V^-1 s ^-1 and on/off current ratio of ca. 10⁶.
