Abstract New phenyl and phenol bis (2-picolyl) amine (Dpa) derivatives have been synthesized in order to generate zinc chelates for imidazole anion receptors. Previously, binuclear phenolic zinc and copper chelates have shown affinity for pyrophosphate and guanidine anions, respectively. Herein we report significant imidazole affinity increasing from 2.38× 10 6 to 2.90× 10 7 for phenol-bridged binuclear zinc–Dpa chelates, as ...
