Abstract A potential fluorescent probe, N'-acetyl-2-((4-methyl-2-oxo-2H-chromen-7-yl)oxy)acetohydrazide (HMC1) was designed on the basis of photoinduced electron transfer (PET) and synthesized using cheap starting materials. HMC1 was found to be highly efficient as a Cu 2+ ion quencher with a detection limit of 0.64 μM (~ 40 ppb). The binding mode of HMC1 towards Cu 2+ was evaluated by 1 H NMR, LC-MS and FT-IR techniques. In addition, cellular imaging studies further exhibited that HMC1 could… CONTINUE READING
