Synthesis of End-capped Regioregular Poly(3-hexylthiophene)s via Direct Arylation

The synthesis of regioregular head‐to‐tail poly(3‐hexylthiophene)s capped with aryl groups (Ar‐HT‐P3HTs) has been accomplished by palladium‐catalyzed polycondensation of 2‐bromo‐3‐hexylthiophene (1) via direct arylation. A variety of aryl groups are installed at the initiated end in 86%–98% selectiv...
