| Popis: | Precise modulation of cation binding affinity was accomplished by the efficient two-step conversion of a newly synthesized macrocyclic ligand H4L2 having a 24-crown-8-like cavity and two saloph moieties. The conversion of H4L2 into L2Ni2 resulted in a 120-fold enhancement in the binding affinity towards Cs+. The electrochemical reduction of L2Ni2 further enhanced the recognition ability by 3 orders of magnitude. |
