• 論文の詳細を見る

• The complex formations of a (1→3)-β-D-glucan with seven direct azo dyes having the same backbone bisazo structure but different side groups were studied by means of visible spectroscopy All the dyes showed red shifts (color change) by the addition of the glucan in an alkaline solution where the glucan takes an ordered conformation, indicating complex formations. The degree of the red shifts depended on the hydrophobicities of the side group at the phenyl groups of the dye backbone structure: methyl>hydrogen>methoxy. Amino groups attached to the backbone naphthalene groups contributed to the red shifts more than hydroxyl groups did. Whereas, a sodium sulfonate group was considered to disturb the complex formaiton.
