Abstract
A pyridoxal-based fluorescent probe HL was synthesized for the detection of Cu2+ in methanol with moderate selectivity. Upon addition of Cu2+, to the solution of the probe in methanol exhibited a remarkable change in emission at 500 nm. With the limit of detection of 10 μM, the probe could well meet the recommended (less than 32 μM in drinking water) of the World Health Organization (WHO). The intracellular Cu2+ imaging behaviour of HL was carried out on HeLa cells.
