An Americium‐Containing Metal–Organic Framework: A Platform for Studying Transplutonium Elements

The synthesis, structure, and spectroscopic characterization of the first transplutonium metal–organic framework (MOF) is described. The preparation and structure of Am‐GWMOF‐6, [Am2(C6H8O4)3(H2O)2][(C10H8N2)], is analogous to that of the isostructural trivalent lanthanide‐only containing material GWMOF‐6. The presented MOF architecture is used as a platform to probe Am3+ coordination chemistry and guest‐enhanced luminescent emission, whereas the framework itself provides a means to monitor the effects of self‐irradiation upon crystallinity over time. Presented here is a discussion of these properties and the opportunities that MOFs provide in the structural and spectroscopic study of actinides. Das erste Transplutonium‐MOF (Metall‐organisches Gerüst), [Am2(C6H8O4)3(H2O)2]⋅(C10H8N2), enthält dreiwertiges Americium und wird in Form von Am‐GWMOF‐6 erhalten. Es hat eine analoge Struktur wie das dreiwertige Lanthanoid‐MOF GWMOF‐6 und dient als Plattform zur Untersuchung der Am3+‐Koordinationschemie und der gastmolekülverstärkten Lumineszenzemission.
