Abstract

A chiral recognition event plays a crucial role in fields such as pharmaceutical design, asymmetric catalysis, and racemic mixture separation. A first example is presented of new targeted square-like sulfonylcalix[4]arene-supported {Co^II₁₆}-coordination cage formation, by exploiting edge-centred chirality induction, capable of selective D-/L-α-pinene adsorption.
