Aggregation Behavior of Cyclodextrin-Based [3]Rotaxanes

Today’s #cyclodextrin:
I have shared several papers and patents already on the fascinating and widespread applications of rotaxanes, from cosmetics through drug delivery to advanced materials.
In this paper Yosuke Akae and Patrick Theato report on an important practical aspect of their use, particularly on the aggregation of cyclodextrin (CD)-based [3]rotaxane, which forms a hexagonal packing type aggregation derived from hydrogen bond formation among CD units in a similar manner to polyrotaxane species. This aggregation could be controlled by solvent type on dispersion treatment, axle end structures, and modification of CD.
