Nuclear Magnetic Resonance Investigation of a Sodium Dibutyl Phosphate/Water Lyotropic Mesophase

2H and 31P NMR have shown that concentrated aqueous solutions of sodium dibutyl phosphate (NaDBP) give rise to a lamellar mesophase for NaDBP mole fractions varying from 0.1 to 0.2 in a temperature range T=285-340 K.By cooling the samples from the isotropic phase in a magnetic field the formation of a discotic DM II mesophase is observed.Different models of water reorientation are proposed to account for the 2H and 17O quadrupole splittings.Nuclear relaxation experiments show that, in this particular system, water molecules reorient preferentially about the direction of an oxygen lone pair orbital.

Linear coordination polymers based on aluminum phosphates: Synthesis, crystal structure and morphology

Several aluminum tris(diorganophosphates) have been synthesized and characterized via elemental analysis, NMR, FT-IR and Raman spectroscopy, as well as powder XRD, and SEM. Single-crystal X-ray diffraction studies revealed that the aluminum tris(diethylphosphate) crystal structure comprises two crystallographically nonequivalent catena-Al[O2P(OEt)2]3 chains propagating along the c-axis. Their parallel orientation favors the formation of closely packed hexagonal domains. PXRD data suggest that other homologues have a similar structure, with the interchain distance closely corresponding to the dimensions of organic ligands. They are also susceptible to a reversible dissociation to ionic species under the effect of primary amines. This feature can be utilized for the synthesis of epoxy nanocomposites.The Royal Society of Chemistry.
