Chain confinement promotes β-phase formation in polyfluorene-based photoluminescent ionogels

The synthesis of photoluminescent conjugated polymer silica ionogels using sol-gel chemistry is described. Cooperative self-assembly of an ionic liquid, the silica precursor and poly(9,9-dioctylfluorene) (PFO) via hydrogen bonding and π-stacking interactions drives formation of the PFO β-phase.
