Synthesis and Electronic Properties of Novel 5,7‐Diazapentacene Derivatives

A route to the synthesis of novel 5,7‐diazapentacenes and some preliminary studies on their properties is reported. A single crystal X‐ray diffraction study of the dihexyl derivative showed it had formed a dimer during the analysis. The materials possess lower lying frontier orbitals than pentacene and may have potential applications in organic electronic devices. This synthetic method may be applicable to the synthesis of other azaacenes. Acenes high! A route to the previously unknown 5,7‐diazapentacene skeleton has been developed and the electronic properties of the new acenes studied.
