过去一段时间里, 用于光电器件的可溶液加工有机半导体材料已经取得了巨大的进步. 寻找新的共轭骨架一直是改善器件性能的研究重点. 相比之下, 通常认为只有增溶作用的柔性链的发展一直没有引起足够的重视. 本文希望通过总结近年来有关柔性链在调控有机半导体光电性能方面的研究进展, 探讨柔性链的类型、长度、密度、取向以及节点等对材料光电性能的影响作用及规律, 以期深刻理解柔性链在调控有机半导体光电性能中的作用, 为进一步优化高性能有机半导体材料的分子结构设计提供参考和指导.

In the past decades, great progress has been made in solution-processed organic semiconductor materials for optoelectronics. Tremendous efforts have been focused on the design of new π-conjugated backbones. In contrast, the effects of flexible chains, which are usually used as solubilizing groups, on the functional properties have been less investigated. In this report, we highlight the effects of flexible chains in organic semiconductors, including the influences of types, length, density, orientation, branching points. This would shed light to further understand the roles of flexible chains on modulating the functional properties of organic semiconductors for optoelectronic devices and thus facilitate the rational design and development of high-performance organic optoelectronic materials.
