The first example of a π-conjugated polymer incorporating boron difluoride (BF2) formazanates is introduced. The film-forming properties, controllable reduction chemistry, and low optical band gap (ca. 1.4 eV) of the polymer make it an excellent candidate for use as a light-harvesting n-type semiconductor in organic electronics. Comparison of the polymer to model compounds confirmed that its unique optoelectronic properties can be directly attributed to the presence of the BF2 formazanate repeat unit and that the [Pt(PBu3)2]2+ unit must also be present to achieve the narrow band gaps observed.
介绍了首例包含硼二氟化物（BF2）甲腙盐的π共轭聚合物。该聚合物具有成膜性能、可控还原化学性质和低光学带隙（约 1.4 eV），是用作有机电子中光收集 n 型半导体的优秀候选材料。将该聚合物与模型化合物进行比较，证实其独特的光电性能可直接归因于 BF2 甲腙盐重复单元的存在，并且必须存在[Pt(PBu3)2]2+单元才能实现观察到的窄带隙。
