Poly(3‐hexylthiophene)‐ block ‐poly(tetrahydrofuran) was synthesized by cationic ring‐opening polymerization of tetrahydrofuran (THF) using a poly(3‐hexylthiophene) macroinitiator. Poly(3‐hexylthiophene) macroinitiator used for the ring‐opening polymerization of THF was synthesized by reacting the hydroxypropyl end‐group with trifluoromethanesulfonic anhydride in the presence of 2,6‐di‐ tert ‐butylpyridine. 1 H NMR spectroscopy and SEC data confirmed the formation of the di‐block copolymers. Field‐effect mobility of poly(3‐hexylthiophene)‐ block ‐poly(tetrahydrofuran) was measured in a thin‐film transistor configuration and was found to be 0.009 cm 2 · V −1 · s −1 .
