The synthesis and photophysical properties of a series of 5-(2,2′-bipyridyl)acetylene-extended dithieno[3,2-b:2′,3′-d]phospholes involving one and two of the latter units are reported. Their molecular scaffolds were found to show limited solubility that could, however, be addressed with the installation of solubilizing groups at the bipyridine unit or the dithienophosphole scaffold, respectively. The photoluminescence features of the new π-conjugated oligomers could be manipulated through complexation to a variety transition metal species (Zn, Pt, and Ru), resulting in polarizable systems with intramolecular charge transfer and/or phosphorescence features, or redox-switching.
