Design and Synthesis of Novel Fluorescent Phthalimide Based Silatranes: Ratiometric Estimation of Mg~(2+) Ion

摘要

Organosilicon analogues of nitrogen-substituted phthalimide were synthesized and characterized by NMR (~1H and ~(13)C), 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 Mg~(2+) over other tested metal ions.
