Semiconducting polymers have gained immense interest over the past few years, in part stimulated by their potential application as active layers in organic electronic devices such as photovoltaic cells, light emitting diodes, and field-effect transistors. Among these polymers, regioregular poly(3-hexylthiophene) (P3HT) has been widely studied because of its good solubility, processability and excellent electronic properties. Herein will be presented a study on the modifications of the P3HT structure and its effect on polymer self-assembly as it relates to device performance in field effect transistors. Furthermore, the application of the Grignard metathesis method to other heteroaromatic compounds will also be discussed, as this method has led to the facile synthesis of all-conjugated block copolymers for optoelectronics.
