摘要

5,6,11,12-四氮杂并四苯（TANC）来自氮杂蒽家族，是一种易于合成的电子受体。为了进一步提高 TANC 的电子亲和力，我们开发了一种具有单共价键的扩展二聚体双 TANC。遗憾的是，较大的双 TANC 溶解性很差。在双 TpTANC 中，这一点得到了显著改善，双 TANC 的两端都以三庚烯（Tp）封端。bi-TpTANC 在溶液中的电化学特性证实了其较高的电子亲和性，其 LUMO 电平为 -4.1 eV，使其成为一种潜在的实用 n 型材料。更多信息，请参阅 H. Kamebuchi、M. Tadokoro 及其合作者的研究文章（DOI: 10.1002/chem.202400632）。

Front Cover: Covalently Linked 5,6,11,12-Tetraazanaphthacene Dimer and Its Triptycene-Capped Derivatives as Electron Acceptors (Chem. Eur. J. 50/2024)

5,6,11,12-Tetraazanaphthacene (TANC), from the family of azaacenes, is a conveniently synthesised electron acceptor. To further increase the electron affinity of TANC, an extended dimer bi-TANC with a single covalent bond was developed. Regrettably, the larger bi-TANC had only severely poor solubility. This has been dramatically improved in bi-TpTANC, in which both ends of bi-TANC are end-capped with triptycene (Tp). The electrochemistry of bi-TpTANC in solution confirms its higher electron affinity with a LUMO level of −4.1 eV, making it a potentially practical n-type material. More information can be found in the Research Article by H. Kamebuchi, M. Tadokoro and co-workers (DOI: 10.1002/chem.202400632).

期刊介绍： Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
