A highly selective fluorescent sensor for Cu2+ based on a covalently immobilized naphthalimide derivative.
In this paper, we describe the fabrication and analytical characteristics of fluorescence-based copper ion-sensing glass slides. To construct the sensor, a naphthalimide derivative N-allyl-4-(bis(pyridin-2-ylmethyl)amino)ethylamino-1,8-naphthalimide (1) with a terminal double bond was synthesized and photo-copolymerized with 2-hydroxyethyl methacrylate (HEMA) on a glass surface treated with a s...
متن کاملA Pyridine-Containing Cu2+-Selective Probe Based on Naphthalimide Derivative
A new fluorescent probe P derived from naphthalimide bearing a pyridine group has been synthesized and characterized. The proposed probe P shows high selectivity and sensitivity to Cu2+ in aqueous media. Under optimized conditions, the linear response of P (2 μM) toward Cu2+ was 0.05-0.9 μM in ethanol-water solution (3:2, v:v, 50 mM HEPES, pH 7.4), and the detection limit was 0.03 μM.
متن کاملTriarylborane substituted naphthalimide as a fluoride and cyanide ion sensor.
Triarylborane substituted naphthalimide 3 was designed and synthesized by the Sonogashira cross-coupling reaction. The electronic absorption and emission spectra of the triarylborane naphthalimide 3 show red shifted absorption and emission as compared to 4-bromonaphthalimide 2. The sensing behaviour of 3 was studied for different anions. The triarylborane naphthalimide 3 selectively detects F(-...
متن کاملA naphthalimide-based fluorescent sensor for halogenated solvents.
A fluorescent sensor for halogenated solvents termed AMN is reported. AMN shows strong fluorescence in most halogenated solvents (QE > 0.1) but weak fluorescence (QE<0.01) in most non-halogenated solvents. In chlorinated solvents, the fluorescence intensity decreased with the reduction of chlorine content. On the contrary, in brominated solvents the fluorescence intensity increased with the red...
متن کاملA Dual colorimetric and Fluorometric Anion Sensor Based on Polymerizable 1, 8-Naphthalimide Dye
A new polymerizable fluorescent sensor based on the photoinduced electron transfer PET for the selective determination of fluoride ions in DMF solutions has been synthesized. The sensing system was prepared by incorporating 4-Amino-1,8-naphthalimide derivatives containing thiourea side chain at the amino moiety AFTN as a neutral F- selective flourophore and was characterized by use of the DSC, ...
