Polysilafluorenes (PSFs) are an important class of light-emitting conjugate polymers noted for their characteristic brilliant solid state blue luminescence, high quantum efficiency, excellent solubility, and improved thermal stability. These polymers are also reported to have superior electron conductivity to polyfluorenes. The higher electron affinity and conductivity, which are particularly promising for OLEDs, originate from σ*− π* conjugation ...
