Abstract Out on a limb : Sonogashira coupling of a suitable AB 2 monomer containing two iodine and one alkyne group forms a hyperbranched conjugated polymer that is studded with iodine end groups (see picture: I purple). These iodine groups are a perfect handle for convenient, efficient, and high‐yielding post‐functionalization to access hyperbranched, fluorescent poly(phenyleneethynylene)s.
