| Abstract Scope |
The vast majority of the literature on actinide chemistry is focused on small compounds (e.g. metals, oxides, small inorganic or organometallic complexes). The emergence of new f-element radioisotopes for use in medicine, combined with a continued push to understand the behavior of nuclear waste in the environment, call for the expansion of f-element chemistry to novel chelators, beyond the classic small molecules. Our team uses macromolecules, whether natural or synthetic, for targeting f-elements, including the most elusive ones. Our multi-pronged strategy led us to investigate actinium and transuranic element chemistries in the presence of the recently discovered lanmodulin protein. Our comprehensive thermodynamic and spectroscopic studies revealed potential new mechanisms for actinide migration in the environment and innovative separation pathways for radioisotopes. Our approach also leverages polyoxometalate macroligands to isolate and characterize f-elements, and revealed otherwise unnoticeable differences between solution-state versus solid-state actinide chemistry, as well as actinide versus lanthanide chemistry. |
