含有外环硫族原子(即硫、硒、碲)的平面芳香族分子的电子和堆积行为的某些方面需要相当大的重新认识。这类半导体曾被认为是电荷转移络合物中应用的下一代p-施主。随着发光二极管、太阳能电池和有机晶体管等新器件技术的出现，人们对电荷转移络合物的兴趣最终减弱。然而，据报道，在过去五年中，在现代有机器件中使用这类材料取得了重大进展。本文综述了近位含硫原子的环外芳烃，总结了合成这些化合物的路线，并对其基本性质进行了分析。特别强调了它们的堆积排列和外环硫族原子对晶体堆积基元的影响。将突出显示这类材料在不同领域的选定应用示例。最后，我们对它们在能源和基本电荷传输/发电等主流应用中的应用进行了预测。
There are certain aspects of the electronic and packing behavior of planar aromatic molecules containing exocyclic chalcogen atoms (i.e., sulfur, selenium, tellurium) which need considerable re-enlightenment. This class of semiconductors was once regarded as next-generation p-donors for applications in charge-transfer complexes. With the advent of new device technologies such as light-emitting diodes, solar cells, and organic transistors, the interest in charge-transfer complexes eventually tapered off. However, significant progress in the use of this class of materials in modern organic devices has been reported over the last five years. In this article, we review the exocyclic arenes with chalcogen atoms in peri-positions, summarize synthetic routes to these compounds and take a close look at their basic properties. Particular emphasis is placed upon their packing arrangements and the effect of exocyclic chalcogen atoms on the crystal packing motifs. Selected example applications from this class of materials in different fields will be highlighted. As a final note, we provide a prediction for their use in mainstream applications such as energy and fundamental charge transport/generation.
