Abstract

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.

摘要

合成并详细表征了两种含锌（II）和两种含钌（II）的π共轭金属聚合物。我们通过尺寸排阻色谱（SEC）、分析超速离心（AUC）和粘度测定法证明，钌（II）金属聚合物是高摩尔质量材料（M(fs) = 20 000 g · mol⁻¹ Ru1 - 2；M(fs) = 34 000 g · mol⁻¹ Ru1），其特性粘度高达[η] = 192 · cm³ · g⁻¹。通过旋涂法制备了聚合物的均匀薄膜，随后能够研究其固态光物理性质。由于形态问题，将与PCBM[60]混合的Ru（II）金属聚合物作为光活性层引入体异质结太阳能电池中，导致效率非常低。
