本文综述了吡嗪类和吡啶类杂并苯化合物的发展历史及其在固态有机电子学中的应用。较大的N-杂并苯是潜在的电子或空穴传输材料，因此应该补充有机电子学中的并苯。由于它们在分子骨架中具有电负性氮环原子，因此与较大的并苯（如并五苯）相比，氧化问题应该不太成问题。本文介绍了较大的（并四苯/并五苯为基础）N，N-杂环并苯的合成和固态包装，以及已知的较大的N-杂并苯及其N，N-二氢衍生物的芳香性和反芳香性的相互作用的问题，也阐明了它们的光学性质。提供了文献综述。
The history and development of pyrazine- and pyridine-type heteroacenes and their use in solid-state organic electronics are discussed and reviewed. The larger N-heteroacenes are potential electron- or hole-transporting materials and should therefore complement acenes in organic electronics. As they feature electronegative nitrogen ring atoms in their molecular skeleton, issues with oxidation should be less problematic when comparing them to the larger acenes such as pentacene. This paper covers the synthesis and the solid-state packing of larger (tetracene/pentacene-based) N,N-heterocylic acenes as well as the question of the interplay of aromaticity and antiaromaticity in the known larger N-heteroacenes and their N,N-dihydro-derivatives; also illuminated are their optical properties. A literature overview is provided.
