摘要：Two new salicylaldehyde Schiff base chemosensors have been synthesized. Their crystal structures, photophysical properties as well as recognition properties for Cu2+ions have also been examined. Their absorption peaks exhibit obvious blue shift upon the addition of Cu2+to a HEPES buffer-methanol (3:7, v/v) solution of the compounds. The compounds are found to be able to recognize Cu2+ions with fluorescence turn-on response in aqueous solution owing to the hydrolysis of the hydrazone bond in the Schiff× ©2014 Elsevier B.V.
