Abstract:
The distinctive chirality change of a polyoxometalate cluster PMo12O403-, induced by cyclodextrins (CDs), was investigated in concentrated aqueous solutions. The host-guest interactions between the used inorganic cluster and the organic CD molecules were then identified to maintain the induced chirality. The supramolecular inclusion at the primary hydroxyl side of CDs was demonstrated to be critical in modulating the formed chirality, while the induced chirality reversal was realized by simply substituting a CD with a supramolecule with larger opening or adding a competitive guest.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Cluster Sampling Method
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...
