It was reported that changes in physical properties comes up when liquid crystal is confined into nano-scale space. On the other hand, TiO₂ has been so extensively studied as photo-semiconductor and photo-catalytic material and typically porous TiO₂ has been applied to a matrix for dye-sensitized solar cells. In this communication, the first results will be shown on one-pot synthesis of TiO₂ nano-particles(NPs) which enables liquid crystalline phthalocyanine to be incorporated inside of the NPs.
