چکیده انگلیسی
S2Ox macrocyclic ligands with (L1: x = 3 and L2: x = 4) and without (L3: x = 3 and L4: x = 4) dibenzo-subunit were employed as extractants. All of the ligands shows silver(I) selectivity and the silver picrate was more extractable with L1 and L2 when compared with L3 and L4. The enhanced extractability for the silver picrate by L1 and L2 was revealed due to the additional stabilization of the complexes, [Ag(L)picrate], by anion-ligand Ï-Ï interaction between the picrate ion and one benzo-subunit in the ligand.
