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

Abstract

The photophysical properties of the copolymer of methyl methacrylate and a new acryloyl derivative of norfloxacin (poly (MMA-co-ACNF)) have been studied in N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), and water solutions. The ability of the poly (MMA-co-ACNF) to detect different metal cations (Fe 3þ , Co 2þ , Ni 2þ , and Cu 2þ ) has been evaluated in DMF solution. The results have shown clearly that only Fe 3þ could be efficiently detected and the plot of log [Fe 3þ ] against the relative fluorescence intensity was linear for Fe 3þ concentration in the range of 6.67 Â 10 À6 to 2.67 Â 10 À4 M.

Synthesis and electropolymerization of a new ion sensitive ethylenedioxy-substituted terthiophene monomer bearing a quinoxaline moiety

“…Iron is a well known metal ion for most organisms, playing a significant role in many biochemical processes such as oxygen metabolism and synthesis of DNA and RNA [8,9]. Therefore, detection of trace amounts of Fe 3+ ion is critical and there have been extensive efforts for the development of selective and sensitive Fe 3+ sensors [10][11][12][13]. Quinoxalines are interesting functional materials due to their fluorescence properties with high quantum yields and can be utilized as fluorescence probes in some chemosensors [14].…”
