In the broad family of heteropentalenes, the combination of two five-membered heterocyclic rings fused in the [3,2-] mode has attracted the most significant attention. The relatively straightforward access to these structures, being a consequence of the advances in the last two decades, combined with their physicochemical properties which match the requirements associated with many applications has led to an explosion of applied research. In this Perspective, we will discuss the recent progress of heteropentalenes' usefulness as an active element of organic light-emitting diodes and organic field-effect transistors. Among the myriad of possible combinations for the different heteroatoms, thieno[3,2-]thiophenes and 1,4-dihydropyrrolo[3,2-]pyrroles are subject to the most intense studies. Together they comprise a potent optoelectronics tool resulting from the combination of appreciable photophysical properties, chemical reactivity, and straightforward synthesis.
在广义的并五苯类化合物家族中，以[3,2-]模式稠合的两个五元杂环的组合受到了最为显著的关注。由于过去二十年的进展，相对直接地获得这些结构，再加上它们的物理化学性质符合许多应用的要求，导致了应用研究的激增。在这篇展望文章中，我们将讨论并五苯类化合物作为有机发光二极管和有机场效应晶体管的活性元件的近期进展。在不同杂原子的无数可能组合中，噻吩并[3,2-]噻吩和1,4-二氢吡咯并[3,2-]吡咯受到了最深入的研究。它们共同构成了一种强大的光电子工具，这是由可观的光物理性质、化学反应性和直接合成相结合的结果。
