摘要：

Chemosensor Z including benzothiazole fluorophore was synthesized and characterized with NMR and HRMS spectroscopic techniques. Z exhibited fluorescence turn-on and ratiometric absorbance detection of Al3+ ions based on the combination mechanism of CHEF and ESIPT processes. Moreover, the stiochiometry between Z and Al3+ were determined 2:1 through job's plot and HRMS, and the limit of detection was determined as 8.47 nM which was qualified in the detection of Al3+ in drinking water. Especially, Z was achieved in fast identification the existence of Al3+ by filter paper, and cell imaging in human stromal cell (HSC).
