- 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.
