HALOGENATED CALIXPYRROLES, CALIXPYRIDINOPYRROLES AND CALIXPYRIDINES, AND USES THEREOF

摘要

The present invention provides halogenated calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles having 4-12 pyrrolic rings with greater stability, enhanced anion and neutral molecule binding affinity, and different binding selectivites as compared to their non-halogenated congeners as judged from ?1H NMR, 19¿F NMR and fluorescence emission spectroscopic analyses.
