Graphical Abstract

Like baking cookies to personal taste, preparation of a library of heterometallic actinide-MOFs allows for tailoring of the “flavor” of material properties. Mixing the radionuclide ingredients in proper ratios reveals structure–property relationships and unique design principles for new classes of actinide-based materials. In addition, the prepared frameworks provide a recipe for novel, pre-designed transuranic MOFs.

Abstract

A novel series of heterometallic f-block-frameworks including the first examples of transuranic heterometallic 238U/239Pu-metal–organic frameworks (MOFs) and a novel monometallic 239Pu-analog are reported. In combination with theoretical calculations, we probed the kinetics and thermodynamics of heterometallic actinide(An)-MOF formation and reported the first value of a U-to-Th transmetallation rate. We concluded that formation of uranyl species could be a driving force for solid-state metathesis. Density of states near the Fermi edge, enthalpy of formation, band gap, proton affinity, and thermal/chemical stability were probed as a function of metal ratios. Furthermore, we achieved 97 % of the theoretical maximum capacity for An-integration. These studies shed light on fundamental aspects of actinide chemistry and also foreshadow avenues for the development of emerging classes of An-containing materials, including radioisotope thermoelectric generators or metalloradiopharmaceuticals.
