摘要：
A novel biphenyl-derived salicylhydrazone Schiff base (BSS) fluorescent probes for highly sensitive and selective identification of Cu2+ has been synthesized. In addition, the recognition has been proved experimentally. The results indicated that the complex forms a 1:1 complex with Cu2+ shows fluorescent quenching. Furthermore, the detection limit of 1.54 x 10(-8) M. More interesting, the probe BSS not only have a good biocompatibility in living cells, but also the sense behavior of Cu2+ in the cell nucleus.
