| Outline of Final Research Achievements |
Selective recognition of saccharides by artificial receptors in water is a challenging goal due to their strong hydrophilicities and complex molecular structures with subtle regio- and stereochemical differences. Here we report the selective and efficient encapsulation of D-sucrose within a coordination-driven molecular capsule from natural saccharide mixtures in water (~100% selectivity and >85% yield). Unlike previous artificial receptors and natural receptors that rely on multiple hydrogen-bonding interactions, theoretical calculations and control experiments indicate that the observed unique selectivity arises frommultiple CH-pi interactions between the sucrose hydrocarbon backbone and the shape-complementary polyaromatic cavity (~1 nm in diameter) of the capsule.
