Anion Association and Macrocycle Encapsulation Tune the Fluorescence of N-Alkylpyridinium-Conjugated Push–Pull Thiazolothiazole Derivatives

Year: 2025

Type: article

Abstract: -alkylpyridinium-conjugated thiazolothiazole (TTZ) fluorophores can be effectively modulated through counterion pairing and macrocyclic encapsulation. A distinct blue emission response to the iodide counterion offers potential applications in anion sensing. Host-guest complexation at the pyridinium site with macrocyclic receptors significantly perturbs the electronic environment of the TTZ core, enabling reversible dual-color emission.
