Functionalised cyclodextrin-based metal-organic frameworks

CD-MOF, an extended framework incorporating the C-8 symmetric cyclic oligosaccharide, c-cyclodextrin (gamma-CD), is based on the coordination of alkali metal cations to alternating alpha-1,4-linked D-glucopyranosyl units on the primary and secondary faces of the gamma-CD tori. Here, we report the synthesis and characterisation of an amino-functionalised CD-MOF that is isostructural with pristine CD-MOF and adsorbs CO2 permanently.
