有机电子学领域的扩展取决于共轭聚合物领域的结构和基础发展。共轭聚合物允许制造低成本、轻质、柔性有机电子器件，在有机光致发光器件（OPV）、有机场效应晶体管（OFET）和有机发光二极管（OLED）中具有显著的应用。这种非凡的应用范围是由于结构的显着多样性，对结构-功能关系的广泛理解以及结构调整的相对容易。这些应用的重要进步和发展主要是由于聚合物结构的演变，通过广泛的合成方法来定制结构和开发改进的聚合条件以限制缺陷。这一观点提供了从早期的协调一致和集中的共轭聚合物研究（1970年代至1990年）到现在的背景，并描述了共轭聚合物结构的剪裁现在如何与应用紧密联系在一起。一个重要的焦点还指向聚合方法如何从用于氧化聚合的侵略性的、非选择性的条件发展到精细调整的过渡金属催化的聚合，其可以提供令人难以置信的高结构保真度并且可以通过C-H活化进行。还讨论了未来工作和新兴领域的领域，如高性能聚合物，而不增加结构和合成的复杂性，识别具有改善的环境稳定性的聚合物结构，灵活和瞬态或生物可吸收的共轭聚合物，混合离子导体，光催化和选择生物应用。
The expansion of the field of organic electronics has hinged upon structural and fundamental developments in the field of conjugated polymers. Conjugated polymers allow for the manufacture of low-cost, light-weight, flexible organic electronic devices, with notable applications in organic photovoltaics (OPV), organic field effect transistors (OFET), and organic light emitting diodes (OLED). This extraordinary breadth of applications is due to the remarkable diversity of structure, an extensive understanding of structure-function relationships, and the relative ease of structural tuning. Important advancements and the development of such applications is largely due to the evolution of polymer structure, enabled by a broad range of synthetic methods for the tailoring of structures and the development of improved polymerization conditions to limit defects. This perspective provides background from the early days of concerted and focused conjugated polymer research (1970s-1990) to the present, and describes how the tailoring of conjugated polymer structure has now become closely tied to application. A significant focus is also directed to how polymerization methods have evolved from the aggressive, unselective conditions used for oxidative polymerizations to finely tuned transition-metal catalyzed polymerizations that can provide incredibly high structural-fidelity and can proceed through C–H activation. Areas for future work and emerging areas are also discussed, such as high-performing polymers without added structural and synthetic complexity, identifying polymer structures with improved environmental stability, flexible and transient or bioresorbable conjugated polymers, mixed-ion conductors, and photocatalytic and select biological applications.
