CRC 1573 / SFB 1573: "4f for Future"
Welcome to the website of the Collaborative Research Centre (CRC) 1573 "4f for Future". CRC 1573 is funded by the German Research Foundation (DFG) and has officially been launched on January 1st, 2023, cf. press releases from DFG and KIT. It is coordinated by Karlsruhe Institute of Technology (KIT), its partners are the University of Marburg (UMR), LMU Munich (LMU, until 09/2023), HHU Düsseldorf (HHU, since 10/2023) and the University of Tübingen (UTÜ).
Materials based on rare-earth metals and their compounds are of crucial importance to our modern high-tech society. Surprisingly, the molecular chemistry of these elements is poorly developed. However, recent progress in this area has shown that this is going to change: In the past years, dynamic developments in the chemistry and physics of molecular rare earth compounds have shifted borders and paradigms that existed for decades.
The chemistry of molecular and nanoscaled rare-earth compounds and their physical properties are in the focus of our CRC “4f for Future”. Its researchers will study synthesis paths and physical properties of new molecular and nanoscaled rare-earth compounds in order to develop materials with unprecedented optical and magnetic properties.

Our established collaboration with Technische Schule Aalen/Germany resulted in a nice group visit headed by their teacher Dr. C. Zimmermann on Jan. 9, 2024. Project leader Prof. Claus Feldmann (AOC) and co-workers gave the young students an overview of our CRC at KIT, a tour of AOC facilities and an introduction into chemistry in general as well as lanthanides in particular. Following an eager discussion and a very positive response, the students "now know everything there is to know between La and Lu".
Congratulations to our associate CRC graduate Bianca Schacherl (co-supervised by Dr. Tonya Vitova, project A3) who has won the KIT Doctoral Award 2023 for her thesis on "Advancing actinide high-energy resolution X-ray absorption/emission spectroscopic tools". With this highly competitive award, KIT honors outstanding doctoral researchers, thereby highlighting the great importance of young scientists at KIT.
Readers of Chemistry & Engineering News (C&EN) elected strontium cyclocene as “standout molecule of 2023“.
In their quest for determining this year’s “most curious, wondrous, and just plain neat molecules“ their choice fell on this new type of supersize sandwich complex created by the groups of F. Weigend, M. Kappes and P. Roesky within the framework of CRC 1573 by coaxing 18 metallocene units to curve into a nanometer-scale ring (a “cyclocene“, cf. Nature paper).
From December 5-7, 2023, our CRC hosted a hands-on workshop on structure solution and refinement using the crystallographic package "Olex2". The event, organized by the scientific software company Olex Sys Ltd., was a complete success, and the approximately 50 participants found the workshop extremely valuable for their everyday scientific work.
Prof. Jana Roithová (Radboud University, Nijmegen/NL), an expert on gas-phase spectroscopy & mass spectrometry and CRC Mercator Fellow, stayed at KIT in mid-November 2023 as a guest of Prof. Manfred Kappes (IPC, KIT). Beyond the intensive scientific exchange with CRC researchers she also gave a very well-received public lecture on her research work "monitoring electrocatalytic reactions".
CRC Mercator Fellow Prof. Roberta Sessoli (University of Florence/Italy), one of the leading experts in molecular magnetism, visited our CRC as a guest of project leader Prof. Annie K. Powell (KIT), in November 2023. In addition to her fascinating lecture "Is there space for magnetic molecules in the second quantum revolution?", she was of course deeply engaged in scientific exchange with CRC researchers and stimulating discussions with young scientists.
Our CRC co-spokesperson Prof. Dr. Stefanie Dehnen (KIT) gave an extended TV interview on "modern chemistry: in search of new compounds" in the framework of the German Südwestrundfunk's (SWR) "Science Talk" series, explaining the development of new substances: "We look at which combinations of elements are not yet available but could have interesting properties." The complete half-hour feature (in German) can be found here.
The first annual Fall Workshop of CRC 1573 was successfully held at Bühl (11.-13.10.2023). Organized by project leaders Prof. Dr. Karin Fink and Prof. Dr. Wim Klopper, the first day was directed at the IRTG members (mainly doctoral researchers) and featured two extended poster sessions and two highly interesting tutorials on quantum-chemical theory (given by the chair persons). This was rounded off by an exciting guest lecture by quantum chemist Dr. Maike Bergeler (BASF SE).
On the second and third day the workshop continued with status reports from the individual project leaders. A total of more than 50 CRC members took part, facilitating various networking activities. The group photo was also taken on this occasion.
As of October 2023, our project leader Prof. Dr. Lena J. Daumann was appointed new W3 professor for Bioinorganic Chemistry at Heinrich Heine University Düsseldorf (HHU). The expert on rare earth metals and their interaction with living organisms joins HHU, after having been at Ludwig-Maximilians-Universität (LMU) Munich for seven years.
We wish her a great start in Düsseldorf and continued high output in research and teaching!
Congratulations to our CRC co-spokesperson Prof. Dr. Stefanie Dehnen (KIT) who was unanimously elected as the future president of the Gesellschaft Deutscher Chemiker (German Chemical Society, GDCh). During her two-year term in office, starting on Jan. 1, 2024, Prof. Dehnen would like to further open up the GDCh and advance it on its path to becoming a modern, diverse and internationally oriented specialist society.
With around 30,000 members, GDCh is one of the largest chemical scientific societies worldwide. It promotes scientific work, research and teaching as well as the exchange and dissemination of new scientific knowledge.
On Sept. 13, 2023, Dr. Ping Yang (Deputy Director of the G.T. Seaborg Institute for Transactinium Science at Los Alamos National Laboratory (LANL), USA) was our guest, following an invitation by project leader Dr. Tonya Vitova.
Dr. Ping Yang gave a great presentation on "Data-driven Separation Design for f-Elements". Following the talk there was an intensive career-path discussion of young international female CRC researchers with Dr. Ping Yang who also provided valuable details, e.g., on the Seaborg Postdoctoral or Summer Fellowship program of LANL.
Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, "4f for Future" researchers were the first to make stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated. The researchers report their findings in Nature.
“These compounds are among the most important complexes used in modern organometallic chemistry,” says CRC 1573 speaker Prof. Peter Roesky (AOC, KIT); "we have now succeeded in forming nano-sized rings for the first time,” Prof. Manfred Kappes (IPC, KIT), and Prof. Florian Weigend (U Marburg) explain. The new nanoring, called ‘cyclocene’ by the researchers, consists of 18 building blocks and has an outer diameter of 3.8 nm.official KIT press release
