Abstract：
:Starch-based polyelectrolyte that contained azo and carboxyl groups was prepared and applied to performed layer-by-layer (LbL) assembly with amino starch. The structure of the starch-based polyelectrolyte was characterized with UV-visible spectroscopy and 1HNMR. UV-visible spectroscopy was also utilized to confirm the assembly characteristic of the starch-based polyelectrolyte. It was found that the adsorption intensity of the sample increased with increasing the layers. The obtained multilayer exhibited a reversible trans-cis photoisomerization when it was subjected to UV and visible light irradiation. The photoisomerization of starch-based polyelectrolyte was able to tune the fluorescence of rhodamine B, which was carried out through LbL assembly and light irradiation. These results suggested that the starch derivative was a good candidate for preparing tunable light-function materials.
