The structure of the Schiff base was revealed with elemental analysis and spectroscopic methods. The colorimetric and fluorescent anion sensor properties of the Schiff base in DMSO were investigated by adding an equivalent amount of anions. In this context, the solution containing Schiff base had a color change after the addition of F - , CN - , AcO - , H 2 PO 4 - and OH - anions, while the color change was not observed with the addition of Br - , I - , SCN - , ClO 4 - and HSO 4 - anions. The anion-binding power of the compound was found to be F - >OH - >AcO - >CN - >H 2 PO 4 - using UV-Vis spectrophotometry, respectively. The antimicrobial activity of the compound was investigated against some microorganisms. The compound showed activity against bacteria and yeast. Schiff base showed a similar effect against both bacteria and yeast. Interactions between the compound and CT-DNA were studied with UV-Vis spectra.
