A Highly Selective Chemosensor Probe for Ag⁺ in 50% THF/H₂O

Abstract:

A highly selective chemosensor for Ag⁺ based on heterocyclic compound Diethyl 6-anilino-5H-2,3-dithia-5,7-diazacyclopenta (cd) indene-1,4-dicarboxylate (D1) was investigated. The deprotonation of N-H was observed easily in spectra of D1 (2.5×10^-5 M) in 50% H₂O/THF solution after NaOH addition, and the deprotonated D1 could interact with Ag⁺, resulted in the sharp decrease of deprotonated absorption. The addition of other metal ions would not produce an obvious change, which means quite extreme selectivity for Ag+ compared with other metal ions. The LOD of the method to detect Ag⁺ was 8.07×10^-8 M. It is indicated that a novel high selective chemosensor for Ag⁺ was build up.
