This study aims to use graphene quantum dots (GQDs) as a fluorescence switching sensor (turn on–off) for the simultaneous detection of cyanide (CN–) and ferricyanide [Fe(CN)6]3– in wastewater samples. The GQDs were synthesized by pyrolyzing solid citric acid. The intrinsic blue color of the solution was observed under ultraviolet irradiation. The fluorescence spectrum was maximized at both excitation and emission wavelengths of 370 and 460 nm, respectively. The fluorescence intensity of GQDs decorated with Hg2+ (turn-off mode as the starting baseline) could be selectively turned on in the presence of CN– and once back to turn-off mode by [Fe(CN)6]3–. The fluorescence switching properties were used to develop a fluorescence turn-on–off sensor that could be used to detect trace amounts of CN– and [Fe(CN)6]3– in water samples. For highly sensitive detection under optimum conditions (Britton–Robinson buffer solution in the pH range of 8.0–9.0, linearity ranges of 5.0–15.0 μM (R 2 = 0.9976) and 10.0–50.0 μM (R 2 = 0.9994), respectively, and detection limits of 3.10 and 9.48 μM, respectively), good recoveries in the ranges of 85.89–112.66% and 84.88–113.92% for CN– and [Fe(CN)6]3–, respectively, were recorded. The developed methods were successfully used for the simultaneous and selective detection of CN– and [Fe(CN)6]3– in wastewater samples obtained from local municipal water reservoirs.

“…An arylpropenone azo containing rhodamine dye ( 122 ) (Scheme 23) showed a preference for Cu 2+ by changing color and increasing absorption intensity at 562 nm in DMSO : water (4 : 1, v/v) and for Fe 3+ by enhancing the fluorescence intensity at 589 nm. 140 Its fluorescence intensity also increased significantly at 595 nm with Cu 2+ . The Authors proposed that ring opening and subsequent 2 : 1 complex (ligand : metal) formation occurred with Cu 2+ while Fe 3+ could not open the spirolactam ring but bound to it through spiro amide O and imine N to one Fe center and amide O and azo N to another Fe center in its 1 : 2 complex (ligand : metal).…”

“…Based on the magnitude of the first hyperpolarizability, the selected compounds may be potential applicants in the development of NLO materials. The magnitude of total static dipole moment (μ) equation [1], mean polarizability total α tot equation [2], anisotropy of the polarizability Δα equation [3] and mean first hyperpolarizability β tot equation [4], can be calculated by using the following equations:…”

“…Diseases like Alzheimer's, anemia, Huntington's, Parkinson's, and some forms of cancer are caused by the overdose or deficiency of ferric ions (Fe 3 + ) in the human body. [1] At present, various metal ions contaminate the water bodies and are a major problem for the environment. This contamination of water resources seriously affects the ecological environment and directly pollutes the soil, resulting in metal ion pollution of agricultural products and thus threatening human health.…”

Abstract2‐Aminobenzochromenes and dihydropyranchromenes represent a unique class of biologically active compounds. We concentrate on the synthesis of biologically active compounds of chromenes using an environmentally friendly, heterogeneous green Amberlite IRA 400‐Cl resin catalyst. These chromene‐structured compounds enable them to be used as fluorescent sensors. The selected chromenes have been used as metal ion sensors to study their photophysical characteristics.
