摘要
π-πstacking,a fundamental noncovalent interaction between aromatic molecules,is essential for enabling charge transport across molecular fragments a process vital to both chemistry and biology.^(1,2)Owing to the widespread importance ofπ-πinteractions in diverse fields,there is considerable interest in precisely modulating the interaction at the single-molecule scale.Studies have shown thatπ-πinteraction can be influenced by adjusting molecular concentration,^(3) applying mechanical forces,^(4) or designing target molecules with enhanced attraction.^(5)However,achieving precise control of intermolecularπ-πinteraction at the single-molecule level without altering molecular conformation or concentration remains a significant challenge.
