Abstract
Abstract 1,2-Bis(2-hydroxymethylphenoxy)ethane was synthesized and characterized by FT-IR and 1 H NMR spectroscopy, and single crystal X-ray diffraction method. The sensing ability of the sensor was studied in the presence of different cations and anions. Following the excitation wavelengths at 275 nm in EtOH/H 2 O (1:9, v/v) and 310 nm in MeCN/H 2 O (1:9, v/v), two distinct emissions at 305 and 356 nm were obtained, respectively. Fe 3+ and CN − ions were successfully detected in EtOH/H 2 O and MeCN/H 2 O mixtures, respectively. While the fluorescence intensity of the sensor quenched considerably in the presence of Fe 3+ cation at 305 nm, it enhanced in the presence of CN − anion at 356 nm. Selectivity of the sensor toward these ions was verified in the presence of a variety of common interfering ions. The detection limits of Fe 3+ and CN − were calculated as 5.4 × 10 −9 mol L −1 and 1.9 × 10 −8 mol L −1 , respectively which shows the high sensitivity of the sensor toward the target ions. Finally, the interaction of the sensor and CN − anion was determined by computational studies.
