| Abstract: | High resolution PMR has been used to study the interaction of electron donor molecules (EDM) (acetone, acetonitrile, pyridine (Py), and dimethylsulfoxide (DMS)) with the hydrate surface structures of graphite oxide.It has been found that only relatively strong EDM (pyridine and DMSO) can destroy the hydrogen-bonded poly-aqua-associates between the graphite oxide layers. A peculiar effect of Py manifests itself in the direct interaction of its molecules with the structural OH groups of the graphite oxide, and of DMSO in the formation of sorption-molecular complexes on the surface of the first hydrate layer, thus screening the solid graphite oxide phase from the bulk of the solution. Acetone and acetonitrile have no noticeable effect in the system.Institute of the Chemistry of Surtaces, Academy of Sciences of the Ukrainian Kiev.
