A sensitive ratiometric fluorescent sensor for zinc(II) with high selectivity.
Sensors (Basel, Switzerland) 20130306 3
A new fluorescent Zn²⁺ chemosensor (P1) based on a functionalized porphyrin was synthesized and characterized. P1 displayed dramatic ratiometric variations in absorption and fluorescent emission spectra upon exposure to Zn²⁺ due to the formation of a 1:1 Zn²⁺/P1 complex. The sensor also exhibited high selectivity and sensitivity toward Zn²⁺ over other common metal ions in the physiological pH range with a detection limit of 1.8 mM. The sensor showed fast response times and excellent reproducibil ...[more]
