    Abstract

    Design of interfaces is an important factor in control of the structures and properties of inorganic-organic hybrid materials, and surface modification with self-assembly monolayers (SAM) can provide interesting inorganicorganic hybrid materials. Here, we focus on SAM-based surface modification of layered inorganic materials via grafting reactions. Layered perovskites can be modified with alcohols using alcohol-exchange reactions to yield alkoxy-modified products. Methods of surface modification with organophosphonic acids have also been developed for modification of layered perovskites and layered potassium hexaniobate. Modification with organophosphonic acids is more attractive than modification with common silylation reagents, since homocomdensation is unlikely to occur under moderate conditions. Exfoliation of SAM-modified materials provides nanosheets covered with SAM. Since these SAM-modified nanosheets exhibit excellent compatibility with polymers as well as interesting, surface properties, they can be employed for preparation of polymer-based hybrid materials. A similar strategy can be employed for surface modification of titanium oxide nanoparticles.
