Benzannulation to porphyrin 2,3 positions has previously been accomplished using various methodologies in the past century, yet there remain limited methodologies to both annulate to the porphyrin periphery and add functional moieties that can then be derivatized for diverse applications. This dissertation describes the development of synthetic routes and characterization of a variety of linearly-annulated, functionalized, β,β'-π-extended porphyrins. There are five chapters in this dissertation, the first of which introduces synthesis and properties of porphyrins and π-extended porphyrins. Chapter 2 describes synthesis of pentacenequinone-fused and pentacene-fused poprhyrins with distinct and new optical absorbance properties. In chapter 3, synthesis and characterization of benzimidazole-fused porphyrins displaying external metal binding capability is described. The synthetic method developed in chapter 3 is extended in chapter 4 to synthesis of bisbenzimidazole-fused porphyrin dimers that show split Soret character, likely due to excitonic coupling between porphyrins of the dimer. Chapter 5 summarizes this dissertation and describes future directions that this dissertation provides foundation for.
