Syntesis and physic-chemical characterization of novel cyclodextrinnanosponges

The reaction between cyclodextrins and suitable carboxylic acids derivatived to afford cross­linked polymers (cyclodextrins nanosponges. CDNS) is described. Different types of CDNS have been synthesized, and the properties of the materials modulated as a function of the type or CD. the chemical nature or the cross-linker and the reaction conditions. The structural characterization of CDNS has been carried out by elemental analysis, DSC. powder X-ray diffraction. scanning electron microscopy, solid state NMR FTIR and Raman spectroscopy.
