Azo Linked Polycyclic Aromatic Hydrocarbons-Based Dual Chemosensor for Cu²⁺ and Hg²⁺ Ions

Abstract

A series of novel azo linked polycyclic aromatic hydrocarbons based sensors (R1-R3) were designed and synthesized in single step. R1-R3 was further developed for the selective and sensitive detection of Cu 2+ and Hg 2+ ions over the other transition metal ions. Receptors exhibit sensible fluorescence enhancement with a detectable naked-eye color changes in presence of Cu 2+ and Hg 2+ ions in aqueous medium. R2 and R3 were also successfully established as a fluorescent probe for detecting Cu 2+ and Hg 2+ ions in RAW 264.7 cells.

Crystal structure of (E)-N1-[(anthracen-9-yl)methylidene]-N4-phenylbenzene-1,4-diamine

“…deviation = 0.027 Å ) and the central and terminal benzene rings of 43.43 (9) and 29.33 (7) , respectively. Some similar ligands have been used as dual chemosensors for the detection of Cu 2+ and Hg 2+ ions (Udhayakumari & Velmathi, 2015) A view of the hydrogen-bonded chains propagating in [001]. Hydrogen bonds are shown as dashed lines; see Table 1 for details.…”

A naphthalene-based azo armed molecular framework for selective sensing of Al3+

“…[17][18][19] Because of naphthalene's excellent rigid plane and extensive p electron conjugated system, it exhibits fine photostability and higher molar extinction coefficients and can be used as a promising template to construct potential colorimetric turnon metal chemosensors. 20 By varying the attached groups at the appropriate positions, the naphthalene-based chemosensor's spectroscopic and photophysical properties, which absorbs primarily in the visible region and fluoresces in the green or blue green region, can be adjusted easily. 21 Naphthalene derivatives are among the most frequently used fluorophores, emitting green spectral regions.…”

A Potential Strategy for Simultaneous Determination of Deferoxamine and Vitamin C Using MCR-ALS with Nanostructured Electrochemical Sensor in Serum and Urine of Thalassemia and Diabetic Patients

“…39 RSM for reliable estimation of the experimental data and prediction of the obtained response 40 was used for investigated effects of variables surface and mathematical model. [41][42][43][44][45][46][47][48][49][50] MCR-ALS is used as a powerful chemometric method for simultaneous determination of deferoxamine and vitamin C. This method was performed to attain information for two the drugs with very high degree overlapping of the oxidation signals obtained from DPV, to deal with this problem for their simultaneous voltammetric z E-mail: m.shabani@kashanu.ac.ir determination for the first time. Using MCR-ALS, the data matrix, can be separated into two matrices consisting of pure i/t and i/E-curves.…”
