Abstract In this investigation we have shown the preparation of carboxylic acid containing new chromophore
: 4-(3-(4-nitrophenyl) thioureido) benzoic acid and its use.The chemical modification of chitosan,
e.g., chitosan- acid salt complexes is done under mild conditions. The synthesis of chromophore
was carried out by conventional methods and the novel polymer complex was soluble in most of
the organic solvents. The modified chitosan was analyzed by various techniques like optical
properties by UV and SHG spectroscopy which showed red shift. The antibacterial activity
showed obvious effect against food pathogenic bacteria. More >
