Abstract

The self-assembly of porous molecular nanocapsules offer unique opportunities to investigate a range of interesting phenomena and applications. However, to design nanocapsules with pre-defined properties, thorough understanding of their structure-property relation is required. Here, we report the self-assembly of two elusive members of the Keplerate family, [Mo132Se60O312(H­2O)72(AcO)30]42- {Mo132Se60} 1 and [W72Mo60Se60O312(H­2O)72(AcO)30]42- {W72Mo60Se60} 2, that have been synthesised using pentagonal and dimeric ([Mo2O2Se2]2+) building blocks and their structures have been confirmed via single crystal X-ray diffractions. Our comparative study involving the uptake of organic ions and the related ligand exchange of various ligand sizes by the {Mo132Se60} and previously reported Keplerates {Mo132O60}, {Mo132S60} based on the ligand exchange rates, revealed the emergence of increased “breathability” that dominates over the pore size as we transition from the {Mo132S60} to the “softer” {Mo132Se60} molecular nano-container.
