Resumo: Novel colorimetric receptors for fluoride ion sensing containing anthraquinone as chromogenic signalling unity and imidazo-2,2´-bithiophene binding sites are reported. Well defined color change was observed upon addition of fluoride ion to acetonitrile solutions of receptors 2. Compounds 2a-c, deprotonated after fluoride ion addition, were studied as metal ion chemosensors in the presence of Zn(II), Hg(II) and Cu(II) in acetonitrile solution, specially compound 2a which displayed a marked change from pink to yellow-gold colors upon complexation.
