A new blue light emitting and electrochromic polyfluorene derivative for display applications

We report a new polyfluorene derivative P(F8-SFX) containing 9,9′dioctylfluorene (F8) and spiro (fluorene-9,9′-xanthene) (SFX) groups on the main chain backbone that performs as both an electrochromic and electroluminescent material.
