Abstract
The fluorescence properties of N-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.
