A new multifunctional benzimidazole tagged coumarin as ratiometric fluorophore for the detection of Cd2+/F− ions and imaging in live cells

Low Molecular Weight Fluorescent Probes (LMFPs) to Detect the Group 12 Metal Triad

“…Additionally, the authors carried out an extensive anion study which showed very little spectral changes for a number of tetrabutylammonium salts (TBAX, where X = F − , Cl − , Br − , I − , OAc − , Siva and Chellapa synthesized a ratiometric benzimidazole tagged coumarin probe 24. Compound 24 could selectively detect Cd 2+ and F − ions in a CH 3 CN/H 2 O (1:9, v/v) HEPES-buffered solutions at pH 7.52, Scheme 9 [178]. The UV-Vis absorption spectrum showed three distinct bands at 292, 342, and 401 nm.…”

Sunlight‐Assisted Photocatalytic Sustainable Synthesis of 1,4‐Disubstituted 1,2,3‐Triazoles and Benzimidazoles Using TiO2−Cu2(OH)PO4 Under Solvent‐Free Condition

“…[25,26] Moreover, based on optical properties of benzimidazoles based materials, they can be also used as dyes, energy storage device, chemosensors and LED applications. [27][28][29] In general, benzimidazoles are synthesized by the reaction of o-phenylenediamines with carbonyl compounds in the presence of different homogeneous and heterogeneous catalytic systems. [30][31][32][33] Even though the synthesis of 1,4-disubstituted 1,2,3triazoles and benzimidazoles are proficiently performed in conventional (heating) reaction condition, product stability and reduction in the yields are the prime disadvantageous of those methods.…”

“…For instance, benzimidazole derivatives are promising choice of pharmacophores in deriving anti‐microbial, anti‐ulcer, antiviral, anti‐cancer, antihypertension, anti‐inflammatory, and so on [25,26] . Moreover, based on optical properties of benzimidazoles based materials, they can be also used as dyes, energy storage device, chemosensors and LED applications [27–29] . In general, benzimidazoles are synthesized by the reaction of o‐phenylenediamines with carbonyl compounds in the presence of different homogeneous and heterogeneous catalytic systems [30–33] …”
