title: Fe3+-ensemble of triazole appended pentacenequinone derivative for "turn-on" detection of fluoride ions.
abstract: Triazole appended pentacenequinone derivative 6 has been synthesized by Suzuki-Miyaura coupling protocol. Compound 6 exhibits selective response towards Fe(3+) ions. Interestingly 6.Fe(3+) ensemble exhibits "turn-on" response towards fluoride ions and thus, makes the 6.Fe(3+) ensemble a novel probe for the selective detection of fluoride ions. Further, derivative 6 coated test strip can detect traces of Fe(3+) and F(-) ions and provide a simple, portable and low cost method for detection of Fe(3+) and F(-) ions in aqueous solution.
