Isomeric dithieno[b , f]phosphepines (DTPs) have been synthesized and their electronic and structural properties were investigated by experimental (UV/Vis, CV, X‐ray) and theoretical (DFT) techniques. A significant dependency of the molecular properties on the isomerically different ring fusions was revealed, which could be ascribed to different conjugation pathways within the DTPs. Moreover, a synthetic method for the π‐expansion of DTPs via direct Pd‐catalyzed C−H coupling was found, which renders these compounds promising candidates for the development of novel organophosphorus functional materials.
