The integration of chemical units of pre-designed chemical function such as recognition sites, redox groups, or chromophore units, may yield hybrid systems combining the unique features of nano-sized materials with the tailored properties of the molecular or macromolecular coatings. Hybridization of organic molecules bearing characteristic properties with nano-sized materials such as nanoparticles, carbon nanotubes, and nanodiamonds is an especially attractive target, as it can improve the physiochemical properties of the nanosized materials, and create new materials possessing the unique properties, which are not appeared in the parent materials. In this context, ionic liquids could be attractive target molecules. Ionic Liquids (ILs) are organic molten salts and are made up of two components i.e. the anion and cation. As both anion and cation can be varied, these materials can be designed for a particular set of properties such as solubility, density, refractive index, and viscosity. The favorable and readily tunable physicochemical properties of ILs, especially imidazolium cation-based ILs have led to intense interest in these materials as alternatives to conventional organic solvents in a range of synthesis, catalysis, electrochemistry and liquid-liquid extractions. However, no extensive studies on the hybridization of ionic liquids with nanomaterials have been made. Recently, we have demonstrated that the tunable property of ILs can be transposed onto the self-assemble monolayers formed with thiol- and trialkoxysilane-functionalized imidazolium salts onto the Au and SiO2 surfaces. It has been also found that through the surface-functionalization of nano-materials with imidazolium salts, the solubility of the ionic nanosized materials can be controlled. These ionic nano-materials could have a potential for variety of applications such as support materials for nanocatalysts. In this seminar, our recent studies on the ionic liquid-nano hybrid will be presented.
