Abstract

We synthesized molecular tweezers composed of two dibenzocyclooctatetraene units, and syn conformers can interact electron-deficient aromatic guests in solution and in the solid state. These compounds were observed as an equilibrium mixture of anti and syn conformers by ring inversion of cyclooctatetraenes (COT) in solution, and substituents group at COT units increase ring inversion energy to lead to the separation of NMR signals of anti and syn conformers at room temperature. In this presentation, properties and binding ability of the molecular tweezers will be discussed in detail.
