Abstract

Novel benzothiazole spiropyran compound,3-benzyl-8′-methoxy-6′-nitro-3H-spiro[benzo[d]thiazole-2,2′-benzopyran],was synthesized as colorimetric and fluorescent chemical sensors for the detection of Fe3+,Cr3+ and Al3+.Due to the special structure and properties of the benzothiazole spiropyran compound,they can be used as important photo-responsive molecules under different light conditions.The properties of the compound was analyzed using UV-Vis spectrophotometer,Fluorescence spectrophotometer,fourier infrared spectroscopy,and nuclear magnetic resonance instrument.It had the advantages of good naked-eye recognition,UV and fluorescence recognition,good anti-interference,faster response time,and lower detection limit.
