Synthesis of a chiral metallo-capsule composed of concave molecules and chirogenesis upon fullerene binding

Abstract

An enantiopure molecular capsule was synthesized quantitatively using complexation of four phosphangulenes as concave molecules with four Zn²⁺ ions and applied to fullerene binding and chirogenesis. The capsule encapsulated selectively fullerene and its derivatives based on the size of cavity. The fullerene C₆₀ incorporated in the capsule exhibited induced-CD signals at the transitions of C₆₀.
