Abstract

A new relative of pentacene: The dialkynylated tetraazapentacene (see figure) was prepared by a two-step synthesis from the corresponding quinone derivative. The heteroacene is an air-stable, dark-blue, crystalline material and is of great interest as a potential organic n-electron-transport material.
