Abstract A novel colorimetric receptor linked to two nitrophenylurea groups was synthesized in good yields, characterized and their chromogenic properties investigated towards various anions F−, Cl−, Br−, I−, OH−, AcO−, H2PO4− and CN− by UV-Vis techniques. The receptor, effectively and selectively, recognized and distinguished the biologically important F− from other anions such as Cl−, Br−, I− etc. in DMSO. This selectivity could be easily observed by the naked eye, indicating that receptor is potential colorimetric sensor for fluoride ion. View Full-Text
