| Abstract: | All‐polythiophene diblock copolymers, comprising one unsheathed block and one fenced block, were synthesized through catalyst‐transfer polycondensation. The unsheathed block self‐assembles through π‐π stacking, thereby inducing microphase separation. Consequently, we have succeeded in creating a microphase separation comprising an ensemble of stacked and isolated polythiophenes. This achievement could be extended to various unexplored applications as a result of the integration of the contrasting functions of the two blocks. |
