Epub 2014 Nov 29.1,5-Dihydroxyanthraquinone (1,5-DHAQ) and in the presence of β-cyclodextrin (β-CD) has been used to find Fe(3+) ion in aqueous solution by UV-visible and fluorescence spectroscopy. The chromo-fluorogenic probe undergoes absorption and emission intensity enhancement upon binding to Fe(3+) ion in pH~7 aqueous solutions. The enhancement of the chemosensor probe is attributed to a 1:1 inclusion complex formation between β-CD and 1,5-DHAQ, which has been utilized as the basis for selective detection of Fe(3+) ion.
