Abstract
N-functionalisation of 3,6-difluoro 2,7-linked carbazole polymers with aryl substituents affords blue emitting materials with good electrolytic stability and moderate quantum yields of fluorescence. Copolymers comprising N-aryl 2,7-linked carbazole repeat units with 3,6-fluoro protecting groups and triaryl amine repeat units afford blue emitting materials with enhanced electrolytic stability and high quantum yields of fluorescence. Both classes of materials were prepared using Suzuki cross-coupling polymerisation methods. The synthesis and characterisation of this new class of materials together with a study of their electrochemical and photophysical properties is presented.
