Urea Receptors which Have Both a Fat Brown RR and a Nitrophenyl Group as a Signaling Group
Sung kyu Lee, Jongmin Kang*
Anion receptor, Urea, Colorimetric receptor, Anion recognition
A new colorimetric anion sensor 1 has been synthesized based on both Fat brown RR dye and a nitrophenyl group. This new receptor 1 could recognize the presence of fluoride ion effectively and selectively by the change of color of solution. In addition, receptor 1 shows higher affinity for acetate, dihydrogenphosphate, and hydrogensulfate than the other anions such as chloride, bromide, iodide, perchlorate, and nitrate in acetonitrile.
