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.

Summary

Introduction

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. In the past two decades, supramolecular chemistry of anions developed into a wide research field that has been extensively reviewed [2,3]. They exhibit such an obvious color change when anion is added that one can detect by naked-eye without resorting to spectroscopic instrumentation [11]. We report the synthesis, characterization and anion-hydrogen binding studies of a bisthiourea compound of N,N′-Bis-(4-nitrophenylcarbamothioyl)phthalamide as shown in Scheme 1.
