Positive homotropic allosteric binding of silver(I) cations in a Schiff base oligopyrrolic macrocycle.
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.
