Notes:
The luminescence properties of a series of lanthanide-substituted ionic polysaccharides have been examined in an attempt to learn about the nature of interactions between the metalions and the polymers. Emission and excitation spectra were obtained for Tb(III) complexes with carboxymethyl cellulose, Sclerox S-1.0, alginate, polygalacturonic acid, amylose sulfate, dextran sulfate, and i-carrageenan. Studies of the chirality associated with the metal-ion binding sites were performed through the use of circularly polarized luminescence spectroscopy. It was learned that the lanthanide ions could form complexes with polysaccharides in the electrostatic manner of polyelectrolytes, and that specific ligating groups could further influence the metal-ion binding characteristics.
