{"abstract":[{"lang":"eng","text":"Effective photoinduced charge transfer makes molecular bimetallic assemblies attractive for applications as active light‐induced proton reduction systems. Developing competitive base metal dyads is mandatory for a more sustainable future. However, the electron transfer mechanisms from the photosensitizer to the proton reduction catalyst in base metal dyads remain so far unexplored. A Fe─Co dyad that exhibits photocatalytic H2 production activity is studied using femtosecond X‐ray emission spectroscopy, complemented by ultrafast optical spectroscopy and theoretical time‐dependent DFT calculations, to understand the electronic and structural dynamics after photoexcitation and during the subsequent charge transfer process from the Fe(II) photosensitizer to the cobaloxime catalyst. This novel approach enables the simultaneous measurement of the transient X‐ray emission at the iron and cobalt K‐edges in a two‐color experiment. With this methodology, the excited state dynamics are correlated to the electron transfer processes, and evidence of the Fe→Co electron transfer as an initial step of proton reduction activity is unraveled."}],"status":"public","year":"2024","type":"journal_article","_id":"56074","author":[{"orcid":"0000-0002-3734-7011","full_name":"Nowakowski, Michał","first_name":"Michał","id":"78878","last_name":"Nowakowski"},{"last_name":"Huber‐Gedert","first_name":"Marina","full_name":"Huber‐Gedert, Marina"},{"full_name":"Elgabarty, Hossam","orcid":"0000-0002-4945-1481","last_name":"Elgabarty","id":"60250","first_name":"Hossam"},{"first_name":"Aleksandr","last_name":"Kalinko","full_name":"Kalinko, Aleksandr"},{"last_name":"Kubicki","first_name":"Jacek","full_name":"Kubicki, Jacek"},{"full_name":"Kertmen, Ahmet","first_name":"Ahmet","last_name":"Kertmen"},{"first_name":"Natalia","last_name":"Lindner","full_name":"Lindner, Natalia"},{"full_name":"Khakhulin, Dmitry","first_name":"Dmitry","last_name":"Khakhulin"},{"last_name":"Lima","first_name":"Frederico A.","full_name":"Lima, Frederico A."},{"first_name":"Tae‐Kyu","last_name":"Choi","full_name":"Choi, Tae‐Kyu"},{"first_name":"Mykola","last_name":"Biednov","full_name":"Biednov, Mykola"},{"full_name":"Schmitz, Lennart","first_name":"Lennart","id":"53140","last_name":"Schmitz"},{"full_name":"Piergies, Natalia","first_name":"Natalia","last_name":"Piergies"},{"first_name":"Peter","last_name":"Zalden","full_name":"Zalden, Peter"},{"first_name":"Katerina","last_name":"Kubicek","full_name":"Kubicek, Katerina"},{"full_name":"Rodriguez‐Fernandez, Angel","last_name":"Rodriguez‐Fernandez","first_name":"Angel"},{"full_name":"Salem, Mohammad Alaraby","last_name":"Salem","first_name":"Mohammad Alaraby"},{"full_name":"Canton, Sophie E.","first_name":"Sophie E.","last_name":"Canton"},{"full_name":"Bressler, Christian","first_name":"Christian","last_name":"Bressler"},{"full_name":"Kühne, Thomas D.","first_name":"Thomas D.","last_name":"Kühne"},{"full_name":"Gawelda, Wojciech","last_name":"Gawelda","first_name":"Wojciech"},{"first_name":"Matthias","id":"47241","last_name":"Bauer","orcid":"0000-0002-9294-6076","full_name":"Bauer, Matthias"}],"publication_identifier":{"issn":["2198-3844","2198-3844"]},"language":[{"iso":"eng"}],"date_updated":"2024-09-05T11:33:44Z","publication_status":"published","title":"Ultrafast Two‐Color X‐Ray Emission Spectroscopy Reveals Excited State Landscape in a Base Metal Dyad","citation":{"mla":"Nowakowski, Michał, et al. “Ultrafast Two‐Color X‐Ray Emission Spectroscopy Reveals Excited State Landscape in a Base Metal Dyad.” <i>Advanced Science</i>, Wiley, 2024, doi:<a href=\"https://doi.org/10.1002/advs.202404348\">10.1002/advs.202404348</a>.","bibtex":"@article{Nowakowski_Huber‐Gedert_Elgabarty_Kalinko_Kubicki_Kertmen_Lindner_Khakhulin_Lima_Choi_et al._2024, title={Ultrafast Two‐Color X‐Ray Emission Spectroscopy Reveals Excited State Landscape in a Base Metal Dyad}, DOI={<a href=\"https://doi.org/10.1002/advs.202404348\">10.1002/advs.202404348</a>}, journal={Advanced Science}, publisher={Wiley}, author={Nowakowski, Michał and Huber‐Gedert, Marina and Elgabarty, Hossam and Kalinko, Aleksandr and Kubicki, Jacek and Kertmen, Ahmet and Lindner, Natalia and Khakhulin, Dmitry and Lima, Frederico A. and Choi, Tae‐Kyu and et al.}, year={2024} }","chicago":"Nowakowski, Michał, Marina Huber‐Gedert, Hossam Elgabarty, Aleksandr Kalinko, Jacek Kubicki, Ahmet Kertmen, Natalia Lindner, et al. “Ultrafast Two‐Color X‐Ray Emission Spectroscopy Reveals Excited State Landscape in a Base Metal Dyad.” <i>Advanced Science</i>, 2024. <a href=\"https://doi.org/10.1002/advs.202404348\">https://doi.org/10.1002/advs.202404348</a>.","ama":"Nowakowski M, Huber‐Gedert M, Elgabarty H, et al.
