Acenes, usually defined as segments of “graphene”, consist of linearly annulated benzene rings, and have attracted considerable interest in both theoretical research and practical applications. However, these compounds generally have undesirable features such as poor solubility, easy oxidation and photodimerization. Thus, scientists have to invest much effort to address these problems and experimentally achieve the desired electronic properties to meet various demands. Herein, we summarize recent progress in the synthesis of pyrene‐functionalized acenes and heteroacenes through the use of pyrene diketone and pyrene tetraketone building blocks. Moreover, the physical properties and applications of these semiconductors in organic semiconductor devices are also described.

使用P-4,5-二酮和P-4,5,9,10-四酮作为构建大并苯和杂并苯的构建基料的最新进展

并苯通常定义为“石墨烯”的片段，由线性环状苯环组成，在理论研究和实际应用中都引起了极大的兴趣。然而，这些化合物通常具有不希望的特征，例如溶解性差，容易氧化和光二聚化。因此，科学家必须投入大量精力来解决这些问题，并通过实验实现所需的电子性能以满足各种需求。在本文中，我们总结了of的二酮和tetra四酮的构建基在of官能化的并苯和杂苯的合成中的最新进展。此外，还描述了这些半导体的物理性质和在有机半导体器件中的应用。
