Abstract

In this paper, synthesis and anntimicrobial properties of a cationic dye were investigated. 4-Amino-N-propyl-1,8-naphthalimide was reacted with chloroacetylchloride followed by N,N-dimethyldodecylamine and a cationic dye was obtained. The product was purified by recrystalization and TLC methods. The chemical structure of the product was characterized by using FTIR, 1HNMR, 13CNMR and elemental analysis. Also, the spectrophotometric data of the synthesized dye was studied. The antimicrobial property of the dye was evaluated by using a minimum inhibitory concentration method (MIC). The product showed considerable antimicrobial effectiveness against either Gram-negative or Gram-positive bacteria in solution.
