The field of fluorescence sensing, leveraging various supramolecular self-assembled architectures constructed from macrocyclic pillar[n]arenes, has seen significant advancement in recent decades. This review comprehensively discusses, for the first time, the recent innovations in the synthesis and self-assembly of pillar[n]arene-based supramolecular architectures (PSAs) containing metal coordination sites, along with their practical applications and prospects in fluorescence sensing. Integrating hydrophobic and electron-rich cavities of pillar[n]arenes into these supramolecular structures endows the entire system with self-assembly behavior and stimulus responsiveness. Employing the host–guest interaction strategy and complementary coordination forces, PSAs exhibiting both intelligent and controllable properties are successfully constructed. This provides a broad horizon for advancing fluorescence sensors capable of detecting environmental pollutants. This review aims to establish a solid foundation for the future development of fluorescence sensing applications utilizing PSAs. Additionally, current challenges and future perspectives in this field are discussed.

“…A bifunctional supramolecular pseudorotaxane sensor (G-WAP) with yellow fluorescence was designed and synthesized exploiting water-soluble cationic pillar [5]arene (assigned as P15) as the macrocyclic molecule and phenazine imidazole as the guest. 30 Upon addition of Ag + , the fluorescence of G-WAP was efficiently quenched due to the bond of Ag + with guests. In the presence of Hg 2+ , the coordination complex G-Hg 2+ -WAP was formed accompanied by an obvious fluorescence color change due to the chelation of Hg 2+ with the nitrogen atom on Apart from acting as analytes, metal ions can also assist pillar[n]arene-based host−guest recognition to construct sensors for nonmetallic ion sensing, for ions such as F − , I − , and CN − .…”

Pillar[n]arene is a novel kind of synthetic supramolecular macrocyclic host characterized by its particular pillar-shaped structure consisting of an electron-rich cavity and two finely adjustable rims. Benefiting from its rigid structure, facile synthesis, ease of functionalization, and outstanding host–guest chemistry, pillar[n]arene shows great potential for diverse applications. Significantly, the host–guest recognition of pillar[n]arene provides a novel approach for chemosensing and imaging. Herein, this Review critically and comprehensively reviews the applications of pillar[n]arene-based host–guest recognition in chemosensing and imaging. The sensing and imaging mechanisms as well as the unique roles and advantages of pillar[n]arene-based host–guest recognition are summarized. In addition, preparations of hybrid materials based on pillar[n]arene and inorganic materials are also introduced comprehensively in the light of chemosensing and imaging. Finally, current challenges and perspectives on pillar[n]arene-based host–guest recognition in chemosensing and imaging are outlined.
