Abstract
Abstract The undesired research results of triazole synthesis were successfully utilized as a simpler, sensitive and selective turn-on fluorescent probe 2 namely chloro-acetic acid 2-benzothiazol-2-yl-phenyl ester (HBT-AcCl) which was synthesized by simple chloroacylation of 2-hydroxyphenyl benzothiazole (HBT). Only one simple chloroacetate, a trigger unit as the reaction site of probe 2 makes it more simple, sensitive and selective for Cys and Hcy over other Amino Acids. The presented probe HBT-AcCl conserves simple structure, reduces the use of extra chloroacetate and improves %atom economy as compare to similar reported probes. Paper strip tests were carried out to explore the potential application for naked-eye detection of Cys under UV lamp. The selectivity of the HBT-AcCl probe for Cys and Hcy is supported by the results of absorbance and emission spectroscopy experiments and theoretical DFT calculations.
