Abstract

Supramolecular interactions between cyclomaltooligosaccharides (cyclodextrins, CDs) and guest molecules depend on various contributions which are still being discussed and may include inter alia release of cavity-bound high-energy water, CDs-ring strain release on complexation, and van der Waals and hydrogen-bonding interactions. 1 Modifications at the secondary hydroxyl groups rim offers an opportunity to introduce recognition features ...
