A new charge‐transfer polymer , containing a benzo[2,1,3]thiadiazole electron‐accepting group and a 2,5‐dihexyloxy‐1,4‐phenylene electron‐donating group, has been synthesized via Pd‐complex‐catalyzed polycondensation. The polymer has a π‐stacked structure in the solid state and forms spherulites. In addition, thin films of the polymer have a golden metallic luster (see Figure).
