Description
Summary: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. More information can be found in the Communication by M. Kivala et al. on page 3474.
