原始语种摘要: A Cu-specific chemosensor probe thiazolyl-hydrazone (BL has been designed and prepared, which provide tridentate chelate NNO coordination mode for Cu with binding stoichiometry of 1:1. The BL solution exhibits a rapid color change from colorless to yellow along with a new intense absorption band at 414 nm upon binding to Cu cation, whereas other metal cations do not induce such a change. The analytical detection limit is 0.75 μM, and the naked eye detection limit is as low as 20 μM. Additionally, the emission signal of BL could be quenched by Cu and Fe with a detection limit of 7.2 μM and 4.3 μM, respectively.
