Abstract

A novel basket-shaped tris(pyrene guanidinium) receptor was synthesized which binds pyrovanadate and pyrophosphate with Ka > 107 M-1. The binding of both anions is associated with quenching of the excimer fluorescence of the pyrenes. The supramolecular vanadate complex catalyzes the bromination of activated C-H bonds and hence is an enzyme mimic of vanadium haloperoxidases.
