Abstract

Triazole appended pentacenequinone derivative 6 has been synthesized by Suzuki–Miyaura coupling protocol. Compound 6 exhibits selective response towards Fe3+ ions. Interestingly 6.Fe3+ ensemble exhibits “turn-on” response towards fluoride ions and thus, makes the 6.Fe3+ ensemble a novel probe for the selective detection of fluoride ions. Further, derivative 6 coated test strip can detect traces of Fe3+ and F− ions and provide a simple, portable and low cost method for detection of Fe3+ and F− ions in aqueous solution.
