Chemical bonding in silicophosphate gels : Contribution of dipolar and J-derived solid state NMR techniques

Résumé

A representative silicophosphate gel was synthesized, starting from orthophosphate groups and pyrophosphate species. At 136°C, a complex mixture of crystalline phases and amorphous components was obtained. A new panel of solid state NMR techniques was implemented, including dipolar based experiments (CP MAS), as well as J-derived techniques, in both homonuclear (31P INADEQUATE-MAS) and heteronuclear (31P/29Si HMQC-MAS) versions. These experiments are suitable for the fine characterization of P–O–P, P–O–Si, P–OH…linkages in silicophosphate gels and materials.
