Abstract
Titanium oxo clusters or nanosized Ti–O particles with hydrophobic or hydrophilic character can be obtained by varying the sol–gel synthesis conditions. These species are potentially interesting nano-building blocks (NBB) in the design of textured materials. The reactivity of well-defined hydrophobic NBB towards different nucleophiles has been characterised and discussed, in order to understand the processes taking place in the formation of meso-organised hybrids. Subsequently, different synthesis conditions were used to generate textured titania-based hybrid phases, using PEO-based surfactants as templating agents. The tuning of the interactions between the template and the different kinds of nano-building blocks allow worm-like and hexagonal titania-based hybrid phases to be reproducibly obtained.
