Positive Homotropic Allosteric Binding of Silver(I) Cations in a Schiff Base Oligopyrrolic Macrocycle

Abstract

The binuclear silver(I) complex of a Schiff base oligopyrrolic macrocycle was prepared in high yield and fully characterized. UV−visible absorption and 1H NMR spectroscopic analyses reveal that coordination of Ag(I) cations is subject to a strong positive homotropic allosteric effect
