Abstract

In this present study, a simple cation chemoprobe 1 bearing naphthol O–H and imine group was designed and synthesized, which was identified as an aggregation induced emission (AIE) active molecule with excited state intramolecular proton transfer (ESIPT) features. In addition, 1 showed both colorimetric detection for Fe3+ and turn-on fluorescence response for Al3+. The binding ratio of 1 to Fe3+ and Al3+ were determined both to be 1:1 via Job's plot and ESI-mass spectrometry analysis. The limit of detection (LOD) of probe 1 to Fe3+ and Al3+ were 0.10 and 0.43 μM, respectively. Moreover, probe 1 could be used to quantify Fe3+ and Al3+ in environmental water samples.
