## Abstract Poly(fluorene)βtype materials are widely used in polymerβbased emitting devices. During operation there appears, however, an additional emission peak at around 2.3 eV, leading to both a color instability and reduced efficiency. The incorporation of the carbazole units has been proven to
## Abstract To prepare a copolymer of fluorene and triphenylamine bearing imidazole groups in the side chain, two synthetic approaches have been designed: the direct copolymerization of the corresponding monomers, and the postβfunctionalization of a precursor polymer. Unexpectedly, the direct copol
