Synthesis and spectroscopic–electrochemical properties of novel ratiometric Hg (II) chemosensor containing Bodipy and the N-phenylaza-15-crown-5 moiety

Abstract

The aryl-amine containing azacrown ether ring and alkyl-chloro boradiazaindacene (Bodipy) were synthesized by Schiff base condensation. The absorption and emission of a novel Schiff base derivative (based on azacrown-Bodipy ) were performed in presence of different cations such as Zn2+, Ga3+, Pb2+, Hg2+, NH4+ Ca2+, Cu2+, Na+, Ni2+, Cd2+ and Cr3+. The complexation property of the Schiff base was studied in dimethylformamide (DMF) by interacting azacrown-ether group and transition metal nitrates-ammonium chloride. The electrochemical behavior of the Schiff base has also been investigated by cyclic voltammetry. All experimental results indicated that the new compound act as a selective ratiometric chemosensor for Hg2+.

A fluorescent sensor-based tripodal-Bodipy for Cu (II) ions: bio-imaging on cells

“…1 H-NMR [CDCl3, 400 MHz]: 8.65 (3H, bs, NH), 8.39 (3H, s, ArH), 7.48-7.15 (12H, m, ArH), 4.48 (CH2, s, 6H,), 2.48 (CH3, s, 18H,), 2.15 (CH2, q, 12H), 1.60 (CH3, s, 18H), 1.12 (CH3, t, 12H). 13…”

“…The use of Bodipy compounds has been reported in the field of fluorescent probes for detection of various cations [7][8][9]. Reportedly, Bodipy is of noteworthy synthetic versatility, high solubility, stability and optical properties Bodipy can also be used as a ligand for metals which require different coordination spheres [10][11][12][13]. Although these Bodipy fluorescent compounds exhibited a good selectivity&sensitivity for the recognition of metal cations, the reported chemosensors were not soluble in pure water [14][15][16][17].…”

Synthesis and Cation Recognition Study of Novel Benzo Crown Ether Functionalized Enamine Derivatives

“…These compounds are commonly considered functional cages because of their ability and selectivity to heavy or alkali metal sensors by using light. Furthermore, dibenzo 18 crown-6 ether derivatives proposed as effective highly selective chemosensor for Hg 2+ and Al 3+ [33][34][35] .…”

Biosensor Design for Detection of Mercury in Contaminated Soil Using Rhamnolipid Biosurfactant and Luminescent Bacteria

“…Jouanneau et al improved heavy metal detection using different strains of E. coli as bioluminescence bacteria [29,30]. Kursunlu et al and Sulak et al designed and prepared fluorescent alkyl-chloride boradiazaindacene (Bodipy) based sensors [31][32][33]. ey showed that Calix [4]-B (obtained by click reaction [31] and a fluorescent Bodipy with alkylchloride terminal) [32], aryl-amine (containing azacrown ether ring and Bodipy) and on/off rhodamine-Bodipy (RB) [33] are appropriate sensors which could be used for high sensitivity detection of mercury ion.…”
