Porous Organic–Inorganic Assemblies Constructed from Keggin Polyoxometalate Anions and Calix[4]arene–Na⁺ Complexes: Structures and Guest‐Sorption Profiles

Abstract

Amphiphilic pore walls facilitate reversible sorption of short-chain alcohols by the 1D microporous organic–inorganic hybrid [1-Na]3[PW12O40] assembled from calix[4]arene–Na+ complex 1-Na+ (R1=R2=H) and the polyoxotungstate anion [PW12O40]3−. The analogous assembly formed with 2-Na+ (R1=tBu, R2=CH2CO2Et) has a 3D microporous architecture.
