Abstract
ICT/CT interplay: A greenish blue TPA-attached pyrazinacene derivative with intramolecular charge transfer (ICT) acts as a nonporous adaptive crystal, selectively recognizing naphthalene with a dramatic red–violet color change via intermolecular CT. This discovery highlights the universal principle of ICT/CT competition for detecting guest pollutants. The illustration depicts naphthalene co-crystallizing with the pyrazinacene at the droplet's edge. More information can be found in the Research Article by K. Nakada, G. J. Richards and A. Hori (DOI: 10.1002/chem.202404487).
ICT/CT相互作用：一种带有分子内电荷转移（ICT）的绿蓝色tpa附着吡嗪二烯衍生物作为一种无孔自适应晶体，通过分子间CT选择性地识别具有显著红紫色变化的萘。这一发现突出了ICT/CT竞争检测客体污染物的普遍原则。该图描绘了萘与吡嗪烯在液滴边缘共结晶的过程。更多信息可以在K. Nakada， G. J.的研究文章中找到。Richards和A. Hori （DOI: 10.1002/chem.202404487）。
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.
