Abstract
Grafted derivatives of graphene oxide (GO), namely N-vinyl-2-pyrrolidone grafted-GO (GO-g-NVP) and oleic acid grafted-GO (GO-g-OLA) were prepared by heating GO in the presence of the corresponding vinyl monomers and the AIBN radical initiator. The lyotropic mesogenic behavior of GO-g-NVP and GO-g-OLA in DMSO‑d6 was proved by deuterium NMR spectroscopy, showing these materials could be used as alignment media for obtaining NMR anisotropic parameters in organic solvent.
