Abstract A novel chiral polyimine macrocycle C‐1 was designed and synthesized by the self‐condensation of dialdehyde dinaphtho[ 2,1‐d:1′,2′‐f ][1,3]dioxepine derivative o ‐phenylenediamine Schiff base formation, corresponding polyamine C‐1H obtained reduction macrocycle. The UV–vis fluorescence spectral studies indicated that both form complex with metal ions in a 1:2 ratio. behaviour upon addition Zn 2+ or Cd showed ‘turn‐on’ response accompanied enhancement at 510 nm six times for 13 . In contrast, revealed ‘turn‐off’ Co , Ni Cu
