Poly(3-hexylthiophene)-b-poly(3-alkenylthiophene) diblock copolymers have been synthesized by McCullough method. The alkene functional group of poly(3-alkenylthiophene) block has been converted  to trialkoxysilane and hydroxyl groups.The ring-opening metathesis polymerization (ROMP) was employed to generate polyethylene graft copolymer.  The measured field-effect mobilities of the copolymers indicated that hydrosilation of the alkenyl groups on the poly(alkenylthiophene) block does not influence the optoelectronic properties of the polymers. The synthesized diblock copolymers displayed nanofibrilar morphology.
