What is it about?
Metastable polymorph of calixarene forms with absolute selectivity only after guest echange for methanol and further guest release
Why is it important?
Metastable polymorph can be used for selective extraction from binary liquid mixtures as shown in citing papers. Formation of this polymorph is an example of genuine molecular recognition where only one compound is recognized by its imprinted image
