Polymers which can be used in p-type materials for organic electronic devices and photovoltaic cells. Compounds, monomers, dimers, trimers, and polymers comprising:
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. Polymers comprising benzodithiophene and/or benzothiadiazole structures can show particularly high performance.
可以用于有机电子器件和光伏电池的p型材料的高分子。化合物,单体,二聚体,三聚体和聚合物包括: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。可以制备不同的高分子微结构,以鼓励多重带隙和广泛而强烈的吸收。羰基可以与相邻的噻吩环相互作用,提供具有刚性的骨架,诱导平面性,并减少和/或消除分子内链扭曲缺陷。包含苯并噻吩和/或苯并噻二唑结构的高分子可以显示出特别高的性能。
