Triphenylamine-containing imine-linked porous organic network for luminescent detection and adsorption of Cr(vi) in water

Abstract

In this study, an imine-linked luminescent porous organic network (PON) has been successfully synthesized by the Schiff-base condensation reaction between 1,2-diphenylethylenediamine and tris(4-formylphenyl)amine. It exhibits strong fluorescence in an aqueous dispersion and can be applied as a luminescent probe for Cr(VI) (CrO42− and Cr2O72−) with high selectivity and sensitivity (LOD for Cr2O72− and CrO42− were below 0.35 μM and 0.4 μM, respectively) in a turn-off manner. The possible luminescence sensing mechanism and the adsorption capacity of Cr(VI) are also discussed in detail.
