Synthesis and characterization of color tunable, highly electroluminescent copolymers of polyfluorene by incorporating the N-phenyl-1,8-naphthalimide moiety into the main chain

Abstract

Block copolymers of <italic>N</italic>-phenyl-1,8-naphthalimide (NPN) moiety in the main polyfluorene chain enables the tuning of emission color from blue to green in PLED devices.
