SYNTHESIS AND SPECTROSCOPIC CHARACTERIZATION OF NOVEL 1,2,3-TRIAZOLYL-BENZOTHIAZOLES

Benzothiazole is an attractive building block in the design of novel fluorescent dyes because of its π-bridging and electron-withdrawing properties as well as high chemical and photophysical stability. In addition, 1, 2, 3-triazoles have great potential in chemical sensing as they can act as a covalent linker between benzothiazole and corresponding functional group or can participate in binding of the target analyte. In this work we present the synthesis of novel 1, 2, 3-triazolyl-benzothiazoles as potential chemosensing molecules for pH and/or heavy metal cations. To further investigate the use of fluorophores in the design of novel sensing materials, the most promising candidate was drop casted on paper strips and examined as pH probe as continuation of our ongoing research.
