Abstract:
Two zinc(II)- and two ruthenium(II) containing p-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 (Mfs¼20 000 g  mol1 Ru1-2; Mfs¼34 000 g  mol1 Ru1) exhibiting intrinsic viscosities of up to [h]¼192 cm3  g1. 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.
