Luminescent Zn(ii)–terpyridine metal–organic gel for visual recognition of anions†
Abstract
Luminescent metal–organic gels (MOGs), prepared with zinc sulfate and 4-[2,2′:6′,2′′-terpyridine]-4′-ylbenzoic acid (Hcptpy), have a good visual recognition ability for anions, which is visible with the naked eye, due to the affinity of anions to the zinc ion center in the MOGs.
