A Naphthalenediimide–Imidazolium Macrocycle for Orthogonal Molecular Recognition

ABSTRACT

A naphthalenediimide‐imidazolium macrocycle is shown to function as a dual‐site supramolecular host for orthogonal molecular recognition. The electron‐deficient cavity encapsulates planar aromatic and metal‐complex guests through π‐interactions, while peripheral imidazolium C2‐H groups selectively recognize halide‐containing metal complexes via hydrogen bonding, enabling complementary binding modes.
