The sub‐10 fs photoinduced electron transfer from alizarin molecules to titania nanoparticles is simulated (see Figure; white: H; black: C; red: O; gray: Ti). The system provides a paradigm of the nanoscale coupling of organic and inorganic species. Remarkably, conduction is possible with photoexcitation below the conduction band and occurs by thermal activation.
