Pentacene

<Pentacene> is a linearly fused five-ring aromatic hydrocarbon, $\mathrm{C_{22}H_{14}}$. Its extended conjugation and crystal packing make it relevant to organic-semiconductor research.
Charge transport in a solid depends on interactions between molecules as well as the electronic structure of an isolated molecule. Pentacene therefore connects molecular orbital ideas with the properties of an ordered molecular material.
