چکیده انگلیسی
⺠C2-symmetric fluorescence and colorimetric anion sensor based on pyrrole derivative was designed and synthesized according to binding site-signaling subunit approach. ⺠The sensor was easily prepared by reaction of pyrrole-2,5-dicarboxaldehyde with 4-nitrophenylhydrazine in ethanol (yield=78%). ⺠In DMSO, the sensor exhibited a visible color change from red to brown upon exposure to anions such as AcOâ and Fâ, however, no obvious color changes were observed when the other anions tested (e. g. H2PO4â, Clâ, Brâ and Iâ) were added. ⺠The sensor showed ratiometric fluorescence responses to anions.
