摘　　要：Novel receptors based on Schiff base bearing phenolic hydroxy groups have been synthesized and characterized.The UV-vis date indicates that a 1∶1 stoichiometry complex is formed between receptors and F-.1H NMR titrations and solvation effect confirmed hydrogen interaction between the receptors and anion.The results indicate that the affinity is related to the number of hydrogen bond.Hence,the receptors 1,2 and 3 can act as fluoride ion sensors even in the presence of other hahide ions.Novel receptors based on Schiff base bearing phenolic hydroxy groups have been synthesized and characterized.
