Porous micellar TiO 2 nanostructures are prepared from self‐assembly of amphiphilic block copolymers with oligomeric titanium precursor (see image). This study also shows a strategy to expand the scope of possible TiO 2 ‐nanostructure morphologies thorugh control of the stereochemistry of block copolymers or selectivity of solvent. This simple scheme for nanoporous TiO 2 can bring new applications with improved performance from in areas such as energy and the environment.
