摘要

We show that polysaccharides (PSs, such as dextran and mannan) can be chemically modified by Os(VI) complexes, yielding electroactive adducts. Os(VI) complexes with different ligands (e.g., temed and 2,2'-bipyridine) produced at pyrolytic graphite electrodes redox couples at different potentials suitable for "multicolor" labeling of PSs and for studies of ligand exchange kinetics. PS-Os(VI)L adducts can be determined not only in their purified forms but also in the reaction mixtures.
