Solid-state luminescence of polymers is currently of theoretical inter
est as well as for application in electroluminescent diodes. The role
of supramolecular structure and morphology on solid-state luminescence
of polymers is explored in rod-coil copolymers containing conjugated
rods. The photoluminescence quantum efficiency of films of the copolym
ers is observed to be dramatically enhanced in the nanocomposite compo
sition region.
