Fluorescent GTP-Sensing in Aqueous Solution of Physiological pH
摘要:
A new water-soluble imidazolium anthracene derivative not only differentiates two structurally similar compounds GTP and ATP but also acts as potential fluorescent chemosensors (as a quencher and an enhancer, respectively) for GTP and ATP in 100% aqueous solution (pH = 7.4, 10 mM HEPES).
A new anthracene dimer connected by two imidazolium moieties has been systematically designed and synthesized as a fluorescent chemosensor for selective binding of H2PO4- over other anions, which have been examined using fluorescence and H-1 NMR and rationalized with ab initio study.
