Abstract

Femto–nanosecond optical transient absorption and nanosecond X-ray absorption spectroscopies resolve the intraligand singlet charge transfer and microsecond triplet excited states in a family of monomeric, dimeric and trimeric Zn-based photosensitizers, with the trimer showing the longest lifetime. The enhanced lifetime of the trimer is attributed to its stabilization by π–π and CH–π noncovalent interactions of the phenanthroline ligands. More information can be found in the Research Article by D. Aravena, L. Lemus, D. Moonshiram and co-workers (DOI: 10.1002/chem.202501682).

覆盖特征：锌（II）单体、二聚体和三聚体光敏剂与微秒寿命的配体内电荷转移激发态通过时间分辨光学和x射线光谱研究

飞-纳秒光学瞬态吸收和纳秒x射线吸收光谱分析了一类锌基光敏剂的配体内单重态电荷转移和微秒三重态激发态，其中三聚体的寿命最长。三聚体寿命的提高是由于邻菲罗啉配体的π -π和CH -π非共价相互作用使其稳定。更多信息可以在D. Aravena， L. Lemus， D. Moonshiram及其同事的研究文章中找到（DOI: 10.1002/chem.202501682）。

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.
