제목 A New Dicyanomethylidene isoporone Based Colorimetric & Fluorometric Sensor for F- and Hg+
초록 We have synthesized a new colorimetric and fluorometric “turn on” sensor which based on the thiophosphinate derivative with Dicyanomethylidene isophorone group (sensor 1). The sensor 1 showed high selectivity and sensitivity towards F- and Hg+ in DMSO/H2O(v/v = 7:3, pH = 8.03). It displays a 30 nm red-shift of maximum absorption band with color change from pale yellow to deep yellow upon addition of F- and Hg+. And the fluorescence emission intensity increased upon addition of  F-, Hg+. The ions(F-, Hg+) selective signaling of sensor 1 did not undergo interference in the presence of other common background ions. Furthermore sensing mechanism of 1+F- was property identified from  1H NMR study.
