Design and synthesis of novel fluorescent phthalimide based silatranes: ratiometric estimation of Mg2+ ion

Abstract

Organosilicon analogues of nitrogen-substituted phthalimide were synthesized and characterized by NMR (1H and13C), ESI-MS and HRMS spectroscopic techniques. The recognition properties of fluorescent silatranes were studied and it was found that the structural variations play important role for metal recognition and one receptor has shown ratiometric estimation of Mg2+ over other tested metal ions
