The characterization of a variety of organic/inorganic multicomponent materials (OIMM) through solid-state NMR (SSNMR) spectroscopy will be reviewed. Many examples of applications to OIMM will be described, based on the observation of different nuclei and the use of various SSNMR methods, such as 1D and 2D techniques, measurements on relaxation and spin diffusion processes. OIMM are a very general category of systems differing, for example, by chemical nature and relative amount of organic and inorganic components, shape and size of the domains, and type of organic-inorganic interface. Some of the most investigated classes of OIMM are organically modified silicates, polymer/clay composites, polymer/inorganic filler systems, polymer electrolytes, stationary chromatographic phases, zeolites, and mesoporous silicas including small organic molecules. The aspects most efficiently investigated by SSNMR and discussed in this review include physical and/ or chemical interactions occurring at the organic-inorganic interface, structural and dynamic behavior of the organic components, and dimensions and dispersion of organic and inorganic domains.
