Conjugated polymers have gained significant interest in recent decades, offering complementary advantages over traditional inorganic electronic materials in ways such as solution processability, mechanical flexibility, and structural diversity afforded via bottom-up organic synthesis. Doping is a crucial aspect for advancing these materials as it adjusts the energies, spatial distributions, and occupancies of the orbitals, affecting the carrier density and mobility. Compared to their p-doping counterparts, n-doping strategies lag behind in their performances. The combination of p-type and n-type polymers is essential for many organic optoelectronic applications, which signified the importance of developing novel n-doping solutions. Traditional electron transfer-type n-dopants, which rely on a low ionization potential for their reactivity, face challenges in processability, reversibility, and sensitivity to ambient conditions. In contrast, C–H σ-dopants operate through different mechanisms. This could open up new avenues to reconcile these conflicts.

C–H σ-掺杂剂介导的共轭聚合物的 n 掺杂：相互设计和多尺度特征

近几十年来，共轭聚合物引起了人们的极大兴趣，与传统无机电子材料相比，其在溶液加工性、机械灵活性和通过自下而上的有机合成提供的结构多样性等方面具有互补优势。掺杂是推进这些材料的一个关键方面，因为它可以调整能量、空间分布和轨道的占用，从而影响载流子密度和迁移率。与 p 掺杂策略相比，n 掺杂策略的性能落后。 p型和n型聚合物的组合对于许多有机光电应用至关重要，这表明开发新型n型掺杂解决方案的重要性。传统的电子转移型 n 掺杂剂的反应性依赖于低电离势，在可加工性、可逆性和对环境条件的敏感性方面面临挑战。相比之下，C–H σ-掺杂剂通过不同的机制起作用。这可能会开辟新的途径来调和这些冲突。
