Fluorescent GTP-sensing in aqueous solution of physiological pH.
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).
