A new
class of nitrogen-containing arene organic semiconductors
incorporating fused indolizine units is described. This system, though
having a zigzag shape, mimics the electronic properties of its linear
analogue pentacene as a result of nitrogen lone pair incorporation
into the π-electron system. Solubilizing trialkylsilylethynyl
groups were employed to target crystal packing motifs appropriate
for field-effect transistor devices. The triethylsilylethynyl derivative
yielded hole mobilities of 0.1 cm<sup>2</sup> V<sup>–1</sup> s<sup>–1</sup> and on/off current ratios of 10<sup>5</sup>.
