rational design. The quantitative conversion and the reversibility between the cage and trithiols through redox reactions were assayed by 1H NMR spectroscopic analysis. The X-ray structure of the synthesized cage-type molecule represents the first successful example of a redox-controlled reversible dimeric capsule linked through covalent disulfide bonds.
