Abstract

original image

Nach einem Flaschenschiff-Ansatz wurden chirale Cobalt(III)-Salen-Komplexe (dargestellt als Kugeln) in die Nanokanäle eines SBA-15-Materials eingeschleust. Die lokale Konzentration der Metallkomplexe und die katalytische Aktivität (z. B. in der hydrolytischen kinetischen Racematspaltung von 1,2-Epoxyalkanen; siehe Schema) waren stark von der Fenstergröße abhängig.
