In this work, 2-(5-methylpyridine-2-yl)imidazole was synthesized to perform a fluorescence sensing system depending on the imidazole derivative as a sensor for Cu2+. According to the required measurements, the imidazole derivative was shown to be used as a sensing agent for Cu2+ with the low detection limit of 1.70 mu M and quantitation limit of 5.65 mu M. Binding ratio was found as 1:1 by using Job's plot. To present the interactions of copper ions and EDTA with the target sensor, H-1 NMR titration measurements were done. Logic gate applications in the presence of EDTA and Cu2+ were investigated. When three outputs (at 372 nm, 395 nm and 418 nm) were examined in 2(4) cases of the two inputs (Cu2+ and EDTA), three different logic gates were obtained as XNOR, IMPLICATION and INHIBIT, respectively.
