The nitrogen atom of azomethine C=N double bond in Schiff base exhibits a strong affinity for transition metal ions. Schiff base derivatives incorporating a fluorescent moiety are appealing tools for optical sensing of metal ions. In this work, fluorescent Schiff base derivatives were synthesized by reacting triazole-linked salicylaldehyde derivative with aminopyrene and aminoanthracene, which are very good fluorophores. These compounds have high potential to be used as metal chemosensors. Detection of a specific type of a metal is very important in terms of biouse of the related compound. In order to determine the sensitivity of the novel compounds, a series of spectroscopic measurements were caried out upon synthesis. Moreover, the metal coordination characteristics of the new compounds were also be investigated theoretically at the level of Density Functional theory with the application of B3LYP/6-31++G(d,p), which is a combination of hybrid exchange function and basis set.
