Multifunctional Luminescent Porous Organic Polymer for Selectively Detecting Iron Ions and 1,4-Dioxane via Luminescent Turn-off and Turn-on Sensing
The
first case of selective Fe<sup>3+</sup> ions and 1,4-dioxane luminescent
sensor based on a porous organic polymer, POP-HT, was synthesized
by reaction of tetra(<i>p</i>-aminophenyl)methane and chromophoric
2,5,8-trichloro-<i>s</i>-heptazine. POP-HT displayed prominent
fluorescence quenching or enhancement in the presence of Fe<sup>3+</sup> ion or 1,4-dioxane. Moreover, an excellent linear relationship was
established between luminescent intensity and the corresponding Fe<sup>3+</sup> ion or 1,4-dioxane concentration. The mechanisms of luminescence
quenching and enhancement were also studied by both experiment and
theoretical calculation. The results of this study suggest that POP-HT
can work as an effective luminescent indicator for qualitative and
quantitative detection of Fe<sup>3+</sup> ions and 1,4-dioxane in
aqueous solution over other metal ions and organic solvents
