Design and one-pot synthesis of a novel pyrene based fluorescent sensor for selective “turn on”, naked eye detection of Ni2+ ions, and live cell imaging
In this work, a novel purine based probe PTAHN was successfully designed and synthesized. PTAHN displayed high selectivity towards Zn2+via turn-on fluorescence. What's more, PTAHN can be proficiently employed for imaging Zn2+ in living cells.
A new “naked-eye” colorimetric and fluorometric chemosensor HAFPA synthesized form both 1 : 1 and 1 : 2 complexes with Zn2+ and only 1 : 1 complex with Cd2+ which can detect intracellular Zn2+ and Cd2+ in A549 cells.
For the rapid, ratiometric, fluorogenic and “naked eye” detection of H2S/S2−, a pro-excited state intramolecular proton transfer (ESIPT)-based receptor, 2-formyl-benzoic acid 2-benzothiazol-2-yl-phenyl ester (FBBP), has been designed.
Herein, we report a new benzothiazole-based azomethine receptor L as a reversible fluorescent sensor for the selective detection of Al3+ in buffered aqueous methanol (20 mM HEPES, pH = 6.0, 50% (v/v) CH3OH).
