Abstract

Chiral mesostructured TiO2 films (CMTFs) were synthesized by a hydrothermal method using L/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 ∼350 nm attributed to the electronic transitions in a dissymmetric electric field.
