Chirality Sensing and Size Discrimination of Anions by Macrotricyclic Cyclen–Disodium Complexes**.


ABSTRACT: Two macrotricyclic ligands composed of two face-to-face octadentate metal chelates were synthesized. These cage-shaped disodium complexes had special recognition ability for various counter anions. Specific chiral dicarboxylates bound to the complexes within the cavity and exhibited chirality induction properties. For instance, -Boc-Asp dianion strongly induced circular dichroism (CD) signals, but -Boc-Glu dianion, which is one carbon longer, did not.
