附简介：

Prof. Dr. Stefanie Dehnen received her Diploma in Chemistry from KIT in 1993 and her Ph.D. degree in Chemistry from Karlsruhe Institute of Technology (KIT) in 1996. She served as a researcher and lecturer at KIT from 1998 to 2005 and subsequently as Professor of Inorganic Chemistry at Philipps-Universität Marburg, where she also had roles as the Executive Director of the Scientific Center of Materials Science and Dean of the Department of Chemistry. In September 2022, she returned to KIT as Professor in Information-Based Materials Design and Nanoscience and Executive Director of the Institute of Nanotechnology. She focused on the synthesis, experimental and quantum chemical investigation of compounds with multinary, in particular multimetallic, cluster-based materials possessing potential as innovative catalysts, white-light emitters, or battery materials. She published many good papers including one paper in Science and three papers in Nature Chemistry. Prof. Dehnen served as Chief Editor of Inorganic Chemistry in 2023. In 2024, she was selected as President of the German Chemical Society. She received many awards including Member (MAE) of Academia Europea; IUPAC Distinguished Women in Chemistry or Chemical Engineering Award; Lappert Prize Lecture awarded by the Royal Society of Chemistry (RSC); Full Member of Berlin-Brandenburg Academy of Sciences and Humanities; Elected Full Member of Leopoldina − German National Academy of Sciences; Full Member of the European Academy of Sciences; Full Member of the Academy of Sciences and Literature, Mainz.

Abstract: The properties of materials based on cluster compounds is largely affected by the diverse compositions and uncommon structural motifs of these nanoobjects, which result in functionalities with great potential for practical use.[1-5] We control the elemental composition by starting out from p-block element precursors that are reacted with further metal complexes or organic compounds. Depending on the chosen elemental combination, the products represent clusters of the metallide or metalate type. Some of the molecular architectures remain unsubstituted, like [K2Zn20Bi16]6– [5] or [An@Bi12]q– (An/q = U/3, Th/4),[6,7] and serve to understand fundamental aspects like electronic properties, cluster formation, and bonding. The aggregation of cluster molecules, such as in [Cs@Ge4(Ge4Se10)4]7–,[8] and the presence of of organic substituents,[10-14] like in [{CpRu}3Bi6]–,[11] [{(Me3Si)2NZn}2Bi6]2–,[12] [{(IMes)Co}2Bi5],[13] or [Sn10O4S16(SBu)4]4–,[14] additionally influence the chemical and physical properties. This leads to unique features, like extreme nonlinear optical response found in materials based on [(StySn)4S6] and related clusters.[15]
