Polymers which can be used in p-type materials for organic electronic devices and photovoltaic cells. Compounds, monomers, dimers, trimers, and polymers comprising:
wherein A1 and A2 each independently comprise a fused ring system comprising at least two fused rings directly covalently linked to the pyrrole rings. Good photovoltaic efficiency and lifetime can be achieved. The R group can provide solubility, environmental stability, and fine tuning of spectroscopic and/or electronic properties. Different polymer microstructures can be prepared which encourage multiple band gaps and broad and strong absorptions. The carbonyl can interact with adjacent thiophene rings to provide backbone with rigidity, induce planarity, and reduce and/or eliminate intramolecular chain twisting defects.
可用于有机电子器件和光伏电池的p型材料的聚合物。 包括化合物、单体、二聚体、三聚体和聚合物,其中A1和A2各自独立地包括至少两个融合环系统,直接共价键连接到吡咯环。 可以实现良好的光伏效率和寿命。 R基团可以提供可溶性、环境稳定性和光谱和/或电子性质的微调。 可以制备不同的聚合物微结构,鼓励多重带隙和宽波段和强吸收。 羰基可以与相邻的噻吩环相互作用,提供具有刚性的主链,诱导平面性,并减少和/或消除分子内链扭曲缺陷。
