Abstract: A new binaphthol derivatized thiosemicarbazone BSB1 has been synthesized and characterized. In DMSO-HEPES( 1: 1,v /v,HEPES 1. 0 × 10-2mol /L,pH = 7. 4) buffered solution,BSB1 exhibited a selective fluorescent recognition to Zn2+ over other tested metal ions with a significant fluorescence enhancement at 572 nm and red shift. BSB1 bind with Zn2+ through 1: 2 stoichiometry with a association constant of 3. 7 × 109L2/mol2.
