Abstrakt:	In this work, two naphthalene scaffolds dangling around a benzene moiety as a colorimetric and fluorimetric probe for Fe3+ in aqueous media have been reported. Recognition processes of Fe3+ were shown to be scarcely influenced by other coexisting metal ions. The probe exhibits a turn on colorimetric and a turn off fluorimetric detection of Fe3+ ions. The association constant for sensor 1–Fe3+ complex was found as Ka = 1.12 × 105 M–1 with the detection limit of 1.7 nM. The chemosensor has been utilized for bioimaging of E. coli cells.
