​Congratulations to Professor Klaus-Viktor Peinemann and group members Luis Francisco Villalobos and Tiefan Huang for their recent research achievements in cyclodextrin films.

A filtration membrane made of crosslinked cyclodextrins is reported. The channel-like cavities of cyclodextrins spawn numerous paths of defined aperture in the separation layer that can effectively discriminate between molecules. The transport of molecules through these membranes is highly shape-sensitive. In addition, the presence of hydrophobic (cavity) and hydrophilic (ester-crosslinked outer part) domains in these films results in high permeances for both polar and nonpolar solvents.
