Two zinc(II)‐ and two ruthenium(II) containing π‐conjugated metallo‐polymers were synthesized and characterized in detail. We could prove by SEC, analytical ultracentrifugation (AUC) and viscosimetry the ruthenium(II) metallo‐polymers to be high molar mass materials ( M fs = 20 000 g · mol −1 Ru1‐2 ; M fs = 34 000 g · mol −1 Ru1 ) exhibiting intrinsic viscosities of up to [η] = 192 · cm 3 · g −1 . Applying spin‐coating we produced homogeneous films of the polymers and could, subsequently, investigate the photophysical properties in the solid state. Introducing the Ru(II) metallo‐polymers mixed with PCBM[60] as photoactive layer in bulk‐heterojunction solar cells resulted in very low efficiencies due to morphology problems.
