Abstract

Abstract: 1, 8 naphthalimide (NI) containing pyridinium nuclei attached by a methylene bridge to the imide nitrogen atom or at the C-4 atom has been obtained by a single-step synthesis. The main photophysical characteristics of NI in organic solvents and water have been studied. A cotton fabric has been modified with chloroacetyl chloride. The possibility of chemical binding of NI to the modified cotton fabric, by quaternization of the pyridinium nuclei and by physical deposition and retention of NI to the surface of the cotton fabric was investigated. The antimicrobial test showed good activity of NI against Gram-positive and Gram-negative bacteria and a fungal strain of the genus Candida, which is preserved after its deposition on cotton fabric. It has been shown that covalent bonding contributed for a better activity compared to the physical deposition and retention of NI on the surface of the cotton fabric.
