Cubically ordered through-film interpenetrating titania and MEH-PPV networks, with an organic–inorganic phase separation of ca. 15 nm, are prepared by co-assembly in solution. Incorporation of the conjugated polymer into the surfactant/titania matrix enhances its photostability, and integration of the hybrid material into a photovoltaic device results in improved performances.
