| Outline of Final Research Achievements |
Crystals of calix[4]arene and thiacalix[4]arene exhibit distinct differences in inclusion properties towards primary alcohols, which originated from the difference in the crystal packing of inclusion crystals according to the property of bridging groups. Selective inclusion of methylamines and switching of guest selectivity by solvent polarity using crystals of thiacalix[4]arene are achieved. It is found that the property of crystals of calix[4]arene can be applied to selective inclusion of aromatic regioisomers. Furthermore, synthesis of linear carboxylic acid-type host molecule having a 2,2'-thiodiphenol structure and selective inclusion of amine isomers using it are succeeded.
