Polyfluorene based conjugated polyelectrolyte/silica nanocomposites are fabricated using sol‐gel processing. Ionic termination groups on the conjugated polyelectrolyte lateral chains are shown to control the interaction at the inorganic‐organic interface, leading to macroscale homogeneity and nanophase separation in a single material. The extent of nanophase separation is determined by the nature of the ionic groups, which may provide a means of controlling donor‐acceptor distances in hybrid systems.
