Fluorescence emission studies of 4-(2-furylmethylene)-2-phenyl-5-oxazolone embedded in polymer thin film and detection of Fe3+ ion

Fluorescence Property of Poly (MMA-co-ACNF) and Its Ability to Detect Fe3+Ion

“…The results revealed that the new poly (MMA-co-ACNF) has a high selectivity and sensitivity to Fe 3þ cations and could be a reliable sensor of Fe 3þ pollution. 6.67 Â 10 À6 , (c) 1.33 Â 10 À5 , (d) 2.0 Â 10 À5 , (e) 2.67 Â 10 À5 , (f) 3.33 Â 10 À5 , (g) 4.67 Â 10 À5 , (h) 6.67 Â 10 À5 , (i) 1.00 Â 10 À4 , (j) 1.33 Â 10 À4 , (k) 1.67 Â 10 À4 , (l) 2 Â 10 À4 , and (m) 2.67 Â 10 À4 mol L À1 . The poly (MMA-co-ACNF) concentration is 5.0 Â 10 À3 mol L À1 .…”

“…An organic supra-molecular compound synthesized from pyrochatechol units was previously used as a stable chelating agent for Fe 3þ in solution. [5] The azlactone derivative dye embedded in plasticized PVC matrix has been used in monitoring Fe 3þ by Ozturk et al [6] Grabchev et al [7] evaluated the ability of the naphthalimide derivative called polyamidoamine dendrimer to detect metal cations in acetonitrile by monitoring the quenching of the fluorescence intensity. However, a limited number of studies reported the use of optical polymer sensors designed by grafting dyes on the polymer chain to avoid the pervasion out of the small molecule in use.…”

Photochemistry and Photophysics in Phenyloxazolones

“…This reaction consists in heating aromatic aldehydes with hippyric or aceturic acids in the presence of acetic anhydride and sodium acetate. The next development in the part of preparation and investigation properties of compounds based on oxazolones was done to describe photochemical and photophysical properties of these compounds [5]. This paper describes the detailed study of a photochemical reaction where 4-benzyliden-2-phenyloxazolin-5 derivatives take part.…”

Optical Determination of Glucose with Glucose Oxidase Immobilized in PVC together with Fluorescent Oxazol‐5‐One Derivatives

“…Oxazolone is a class of heterocycle that has favorable photophysical and photochemical properties in crystalline state (Icli 1999;Ozturk 2007). Several authors have investigated the luminescence properties of azlactones and very low fluorescence efficiencies have been reported for solutions in different solvents (Krasovitskii 1988).…”
