The macroscopic functions and properties of conjugated polymers depend on their microcosmic morphology and microstructure in the solid state. However, such morphology and microstructure from molecules to solid states are complicated. Therefore, it is a significant challenge to reveal the relationship among molecular structures to the complex microstructure and finally to device functions. This review focuses on the formation, behavior, and evolution of solution-state aggregation of conjugated polymers, which can influence and even determine the solid-state morphology and microstructure, ultimately clarifying the relationship between the microstructure and the properties of conjugated polymers. The critical role of solution-state aggregation is highlighted from a theoretical understanding of molecular interactions between polymer chains (conjugated backbones and/or flexible side chains) and solvent molecules. We highlight the recent progress on high-performance polymer-based devices through the solution-state aggregation strategy. Furthermore, we summarize the challenges and essential research direction on the solution-state aggregation, which will be addressed and established in the future. Therefore, an in-depth understanding of polymer aggregation will advance the development of high-performance conjugated polymers in various functional devices.

通过溶液态聚集控制共轭聚合物的形态和微观结构

共轭高分子的宏观功能和性质取决于它们在固态下的微观形貌和微观结构。然而,这种从分子到固态的形貌和微观结构是复杂的。因此,揭示分子结构与复杂微观结构乃至器件功能之间的关系是一项重大挑战。本综述重点关注共轭聚合物溶液态聚集的形成、行为和演化,它可以影响甚至决定固态形貌和微观结构,最终阐明共轭聚合物微观结构与性能之间的关系。从对聚合物链(共轭主链和/或柔性侧链)与溶剂分子之间的分子相互作用的理论理解中突出了溶液状态聚集的关键作用。我们通过溶液态聚合策略强调了基于高性能聚合物的设备的最新进展。此外,我们总结了解决方案状态聚合的挑战和基本研究方向,这些将在未来解决和建立。因此,深入了解聚合物聚集将推动高性能共轭聚合物在各种功能器件中的发展。此外,我们总结了解决方案状态聚合的挑战和基本研究方向,这些将在未来解决和建立。因此,深入了解聚合物聚集将推动高性能共轭聚合物在各种功能器件中的发展。此外,我们总结了解决方案状态聚合的挑战和基本研究方向,这些将在未来解决和建立。因此,深入了解聚合物聚集将推动高性能共轭聚合物在各种功能器件中的发展。
