A Highly Selective Fluorescence “Turn on” and Absorbance-Ratiometric Detection of Al3+ in Totally H2O and its Application in Test Paper

A novel naphthalene based fluorescence probe NBDH was designed and synthesized. Probe NBDH exhibited highly selective and sensitive responses towards Al 3+ in HEPES-NaOH buffer solution (pH = 7.4). In addition, the detection of NBDH to Al 3+ could be achieved through dual channels embodied in signif...

Summary:A novel naphthalene based fluorescence probe NBDH was designed and synthesized. Probe NBDH exhibited highly selective and sensitive responses towards Al 3+ in HEPES-NaOH buffer solution (pH = 7.4). In addition, the detection of NBDH to Al 3+ could be achieved through dual channels embodied in significant fluorescent turn-on signal and ratiometric absorbance response. The stoichiometry ratio of NBDH -Al 3+ was 1:1 by fluorescence job’ plot and binging mechanism was further varified by the FT-IR, NMR titration and HRMS. Furthermore, NBDH was achieved in real sample detection, and a series of color test paper were developed for visual detecting Al 3+ ions.
