Allosteric silver(I) ion binding with peripheral pi clefts of a Ce(IV) double decker porphyrin.
[reaction: see text] A cerium(IV) double decker porphyrin (1) bearing four 4-methoxyphenyl groups was synthesized. Compound 1 shows a positive, homotoropic allosteric effect in metal recognition of Ag(+) ion, and the peripheral pi clefts of 1 act as effective binding sites for Ag(+) ion.
