The synthesis of two polyconjugated graft copolymers based on a poly(fluorene‐phenylene) backbone and polystyrene side chains is described here. The two different approaches followed, ATRP growth of side chains from a preformed conjugated backbone and “click” connection of well‐defined polymeric chains to the backbone, led to different results in terms of solubility and material properties. While the ATRP method seems to be responsible of a partially cross‐linked and nonsoluble copolymer, the “click” approach provides a graft copolymer, which is completely soluble, showing atypical spectroscopic properties that are here elucidated.
