Abstract
- Abstract: Herein, we report the synthesis of two lanthanide-based chemosensors, Tb-5 and Eu-6, designed to sense free zinc ions (Zn2+) in aqueous solutions. The Tb-5 complex features a bis(2-pyridinylmethyl)amine moiety as a zinc(II)-responsive lanthanide-sensitising ‘antenna’, while Eu-6 incorporates a quinoline-based moiety for this purpose. Luminescence enhancements of 210% and 340% are observed upon addition of Zn2+ ions to Tb-5 and Eu-6, respectively. Both sensors are selective for Zn2+ ions over several other cations of environmental significance. [Copyright &y& Elsevier]
