Resumo: Imidazoles have been explored over the years as optical chemosensors for their ability to coordinate with analytes, through specific binding sites, especially for ions, provided by the nitrogen heteroatom. Consequently, a novel 2,4,5-triheteroarylimidazole was synthetized bearing indolyl and furyl moieties. The compound was characterized by the usual spectroscopic techniques, and the preliminary chemosensory ability was carried out in acetonitrile and acetonitrile/water (25:75) in the presence of ions with biological, medicinal and environmental relevance. In an aqueous medium, the new compound showed a slight enhancement of fluorescence in the presence of HSO4−. As for cations, an enhancement of the fluorescence was observed upon interaction with Fe2+, Sn2+, Fe3+ and Al3+. On the other hand, a quenching of fluorescence was observed in the presence of Cu2+.
