A chemosensor 1, based on the Schiff base, is easily prepared by reacting tryptophan and 2-hydroxy-1naphthaldehyde in methanol. The optical properties of 1 are investigated in buffered aqueous solution, which displays specific recognition to Zn 2+ , and especially avoids the interference of Cd 2+ wh
