| Abstract |
The interests of designing and synthesizing ion receptors possessing selective sensing abilities for various ions/ion pairs draw great attention due to their application in medicinal and environmental chemistry. Among them, calix[4]pyrroles have been known as anion receptors for various anionic species and variety of modification of the mother macrocycles have been developed. The modifications are generally focused on the β-pyrrolic positions and meso-positions. Usually introduction of substituents at β-pyrrolic positions decreases the anion affinity because of destabilizing steric interactions incurred upon anion binding accompanied with conformational changes. A novel ion-pair receptor must have functionalities that recognize both cations and anions with high affinity and selectivity. In this respect, we here present the design of new calix[4]pyrroles containing heterobicyclic pyrrole as building block. The ion-pair binding properties of the synthesized receptors will be presented in detail. |
