چکیده
|
A cu2+-specific chemosensor probe thiazolyl-hydrazone (bl) has been designed and prepared, which provide tridentate chelate nno coordination mode for cu2+ 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 cu2+ 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 cu2+ and fe3+ with a detection limit of 7.2 μm and 4.3 μm, respectively.
