A general approach for the functionalization of inorganic nanoparticles with polymers is presented. The polymers for functionalization are designed to possess an anchor block and a soluble block. By this approach, TiO2 nanorods can be solubilized up to high concentrations in organic media. Owing to their anisotropic shape, liquid crystalline phases are formed, opening the possiblity of orienting the nanorods macroscopically.
