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, [Mo Se O (H O) (AcO) ] {Mo Se } 1 and [W Mo Se O (H O) (AcO) ] {W Mo Se } 2, that have been synthesised using pentagonal and dimeric ([Mo O Se ] ) 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 {Mo Se } and previously reported Keplerates {Mo O }, {Mo S } based on the ligand exchange rates, revealed the emergence of increased "breathability" that dominates over the pore size as we transition from the {Mo S } to the "softer" {Mo Se } molecular nano-container.
