New synthetic developments towards polymers containing aromatic building blocks in the polymer backbone are described. The synthesis of polyphenylene‐related systems with an improved solubility due to their alkyl substitution is discussed. Via bridging of the phenylene rings a twisting of the aromatic subunits is avoided and the conjugation improved. This concept is extended to ribbon‐type polymers containing 6‐ or 6‐ and 5‐ membered rings. It is demonstrated that during a polycondensation process anthracene can be incorporated into various polymers via C‐O bond formation as well as via C‐C connection. Cycloaddition reactions are presented, allowing for modification and grafting of these polymers. Additionally, the use of anthracene derivatives as initiators in homo and block copolymerisation is shown.
