Abstract The present investigation deals with the preparation of carboxylic acid containing new
chromophore : 4-2-(2-hydroxy-5-(4-nitrophenyl) diazenyl) benzylidene) hydrazinyl) benzoic acid
and its use for chemical modification of chitosan, e.g., chitosan-acid salt complexes under
mild conditions. Optical properties of chitosan acid complexes were evaluated by UV and SHG
spectroscopy which showed red shift. Antibacterial activity of prepared chitosan acid complexes
showed obvious effect against food pathogenic bacteria. The novel polymer complex was soluble
in most of the organic solvents. More >
