Abstract
Imine linked chemosensor has been synthesized and examined for cation recognition properties. The sensor shows strong affinity for Al 3+ over other cations such as Na + , K + , Mg 2+ , Ca 2+ , Ba 2+ , Sr 2+ , Cr 3+ , Mn 2+ , Fe 3+ , Co 2+ , Ni 2+ , Cu 2+ , Zn 2+ , Ag + , Hg 2+ , Pb 2+ , Zr 4+ , Th 4+ and VO 4+ . The resultant Al 3+ complex has been synthesized and characterized on the basis of elemental analysis, mass spectra, and IR spectra. The recognition behavior of this complex was tested towards various anions and the complex has offered an interesting opportunity for the ratiometric determination of HSO 4 − in DMF/H 2 O (7:3, v/v) solvent system. This is the first Al 3+ complex used for the ratiometric determination of HSO 4 − in semi-aqueous medium. ► Imine linked dipodal organic chemosensor has been synthesized. ► Selective detection of Al 3+ through excited state proton transfer mechanism. ► The resulting aluminum complex of this sensor is selective for HSO 4 − . ► The ratiometric determination of HSO 4 − in semi-aqueous medium.
