"Four 1,1'-binaphthalene based bis-urea derivatives bearing aryl groups at end-on nitrogen atoms IIIa-d were synthesized as potential sensor molecules. These receptors show characteristic UV-VIS spectral changes on complexation with anions and they exhibit selective recognition of F- over other halide anions," investigators in Bratislava, Slovakia report.
"Interaction of a fluoride anion with urea NH groups was confirmed by H-1 NMR data. The presence of an electron-withdrawing nitro group in N'-aryls (receptors IIIa and IIIb) appeared to be necessary for naked-eye colorimetric detection," wrote R. Miklas and colleagues, Comenius University.
