| Outline of Final Research Achievements |
Ligands with highly preorganized coordination environment are necessary for the development of high-performance metal extractants, high-sensitivity sensors, and highly functional metal-complex catalysts to attain high affinity and selectivity toward metal ions. In this study, we synthesized OH-X hybrid-type calixarenes having two coordinating functional groups X instead of two distal OH groups of p-tert-butylcalix[4]arene by our previously developed method and evaluated their recognition abilities toward metal ions. By positioning metal ions near the calix framework, we could create high-performance and highly selective metal extractants, palladium complex catalysts showing unprecedented selectivity, and a highly sensitive and highly selective mercury sensor.
