Today’s cyclodextrin post sheds light on the fascinating ability of cyclodextrins to complex not only solids and oils, but also gases!

Researchers Todor Dudev and Tony Spassov from Sofia University explore the intimate mechanism of β-cyclodextrin/gas complex formation and answer intriguing questions.

They investigate how the polarity and size of the guest molecule influence complexation thermodynamics, and which encapsulation process by the host macrocycle is more advantageous. They also examine the major factors governing the formation of the complex between β-cyclodextrin and gaseous substances. The research emphasizes the special role that the cluster of water molecules inside the host’s internal cavity plays in the encapsulation process.
