Abstract: The objectives of this research was to develop the chemistry for the synthesis of a new class of pentacene and tetracene containing polymers and oligomers. These materials were designed to have low bandgap and high charge carrier mobility. The general synthetic routes were developed for this class of materials. The synthesized new molecules and polymers were used for structural property relation studies to understand the effect of molecular structure on solid state packing, energy level and absorption. New molecular design rules were found for high performance electron transporting materials. A general correlation between charge carrier type and the molecular orbital energy levels was obtained for the first time using the large number of compounds synthesized.
