Cyclodextrins (CDs) are of increasing scientific and commercial interest because they are readily available, harmless and well-defined, forming sophisticated supramolecular structures in aqueous media. More than 2,300 publications and more than 1,200 patents appeared in 2015 in which CDs played a significant role. CD chemistry has developed into a very attractive field of research. This series follows "Superstructures with cyclodextrins: Chemistry and applications II" and "Superstructures with cyclodextrins: Chemistry and applications".
