Three‐star‐shaped conjugated polymers containing poly(3‐hexylthiophene) arms and either a triphenylamine or triphenylbenzene core were prepared. The results show the critical role of the core structure on the aggregation of polymers chains and hence optical properties of the star‐shaped polymers. Moreover, the star‐shaped P3HTs exhibited the lower the Shrinking Factor, g ' comparingwith their linear P3HT.
