Chiral polyoxometalate–cyclodextrin frameworks via Mn-mediated assembly: Enhanced stability and catalytic activity

Abstract

The application of polyoxometalate (POM) as building blocks to construct chiral POM-based functionalized frameworks remains a long-standing challenge. In this study, we report a chiral assembly by blending inorganic POMs and organic cyclodextrin (α-CD) molecules on the basis of coordination interactions. {SiW 12 } anions connect with Mn ions (Mn 2+ ) antiparallel to form a unique allinorganic layer with significant voids. The similar α-CD layered structure fills the voids of the POM-Mn layers, which are interwoven to form an organic-inorganic hybrid, which is extended by Na + ions to produce a three-dimensional framework. The stability, chiral separation, chiral catalysis, and proton conductivity of this composite framework are explored.

“…Advanced POM-based functional materials are a complicated and challenging research area. 1–7 The utilisation of organic ligands or complex units to functionalize POMs is a unique method for generating organic–inorganic hybrid materials based on POMs. 8–14 These organically functionalized hybrid POMs have been synthesized by replacing one or more oxo or [MoO x ] n + groups with organic functional groups.…”
