A light‐emitting diode based upon a three‐component hybrid inorganic/organic nanocomposite film , comprising a mesoporous TiO 2 film, a light‐emitting polymer adsorbed to the metal‐oxide surface, and a hole‐transporting polymer interpenetrated into the film pores (see figure), is described: it allows the luminescence and charge‐carrier transport processes to be tuned individually.
