Hydrogen sulfate ion sensing in aqueous media based on a fused pyrimido benzothiazole derivative

A sensitive and selective receptor 3-cyano-4-imino-2-methylthio-4 H -pyrimido[2,1- b ][1,3]benzothiazole ( SVK-1 ) bearing a fused pyrimido benzothiazole structure was developed for the recognition of HSO 4 anions. UV-vis and fluorescence emission spectroscopy were employed for the recognition for H...

Description
Summary:A sensitive and selective receptor 3-cyano-4-imino-2-methylthio-4 H -pyrimido[2,1- b ][1,3]benzothiazole ( SVK-1 ) bearing a fused pyrimido benzothiazole structure was developed for the recognition of HSO 4 anions. UV-vis and fluorescence emission spectroscopy were employed for the recognition for HSO 4 over other anions such as Cl , Br , I , F , AcO , H 2 PO 4 , ClO 4 and NO 3 in an aqueous medium. The receptor 3-cyano-4-imino-2-methylthio-4 H -pyrimido[2,1- b ][1,3]benzothiazole ( SVK-1 ) was employed for the selective sensing of HSO 4 ions in aqueous media.
