A click generated quinoline derivative (1) has been synthesized and used as a fluorescent probe for sequential recognition of Cu2+ and pyrophosphate (PPi) in DMSO/H2O (1:1, v/v, HEPES 20 mM, pH = 7.4) solution. Probe 1 displays high selectivity to Cu2+ ions, and the in-situ prepared probe 1-Cu2+ exhibits high selectivity toward pyrophosphate (PPi) with emission recovery of probe I. Therefore, 1-Cu2+ complex can be applied as a fluorescence turn-on probe for PPi with high selectivity and sensitivity. (C) 2013 Elsevier Ltd. All rights reserved.
