Bundle-like Assemblies of Cadmium Hydroxide Nanostrands and Anionic Dyes

Molecularly flat and extremely long bundle-like assemblies were prepared from cadmium hydroxide nanostrands and polysulfonated dyes. The dye molecules were regularly aligned along with the nanostrands, as confirmed by electron microscopies and UV−vis absorption spectroscopy. Strong electrostatic interaction between the two components was useful to control the fibrous morphologies and optical properties of these organic/inorganic nanocomposites.
