This report from the Luscombe group describes the application of C-H Functionalization in a one-pot approach for the synthesis of poly(3-hexylthiophene), key materials in sensors, coatings and light-harvesting materials.
Through fine-tuning of the reaction conditions and the catalyst ligands control over the degree of branching was acheived. The degree of branching in these structures has a direct and significant impact upon the physical properties of the material. C-H Functionalization was shown to offer excellent levels of control in these systems.
