Abstract

Abstract A novel Schiff-base fluorescent sensor 7-methoxychromone-3-carbaldehyde-((2’-Benzothiazolylthio)-acetyl)) hydrazone (MCAH) was synthesized. The new chemosensor possesses dual PET processes simultaneously introducing by both nitrogen and sulfur donors. Upon binding Al3+, a significant fluorescence enhancement with a turn-on ratio over 500-fold was triggered. The detection limit of MCAH for Al3+ was 3.19×10−8M.
