Anatase TiO2 nanocrystals have been organized into high-surface-area (150–230 m2 g−1) mesoporous films with long-range chiral nematic ordering. The chiral structure of the anatase films causes them to selectively reflect circularly polarized light and appear iridescent. These materials show replication of structural features found in the silica template on nanometer to millimeter length scales.
