An actinyl peroxide cage cluster, Li48+mK12(OH)m[UO2(O2)(OH)]60 (H2O)n (m≈20 and n≈310; U60), discriminates precisely between Na+ and K+ ions when heated to certain temperatures, a most essential feature for K+ selective filters. The U60 clusters demonstrate several other features in common with K+ ion channels, including passive transport of K+ ions, a high flux rate, and the dehydration of U60 and...
Schön symmetrisch wie Fulleren: Anorganisch‐organische Clusterkäfige mit 36 und 60 Uranylperoxid‐Polyedern und 6 bzw. 30 Oxalatgruppen (siehe das Bild eines {U60}‐Clusters) entstehen selbstorganisiert in wässriger Lösung unter Umgebungsbedingungen. Diese Cluster, die sich topologisch von Fullerenen ableiten, wurden für Strukturanalysen kristallisiert und gehen intakt in Wasser in Lösung.
