摘要：

Chiral mesostructured TiO(2)films (CMTFs) were synthesized by a hydrothermal method usingl/d-mannitol as the symmetry-breaking agent and titanium foil as both the substrate and inorganic precursor. Five levels of hierarchical chirality exist in the CMTFs, exhibiting optical activity (OA) at similar to 350 nm attributed to the electronic transitions in a dissymmetric electric field.
