Abstract

Binding of Li⁺ to quadrannulene and its influence on buckybowl functionalization are introduced. The concave-trapped Li⁺ acts as a Lewis acid and the rate of Diels–Alder cycloaddition is enhanced 10⁸ times. A sandwiched bowl-Li⁺-bowl structure is stabilized via concave–cation–convex interactions, indicating the promoted role of Li⁺ in buckybowl assembly.
