π-共轭聚合物由于其优越的光电和机械性能而具有广泛的应用。这些特性本质上取决于聚合物的排序，包括结晶度、取向、形态、域大小和 π-π 相互作用。编程，或通过明确定义的输入有意控制 π 共轭聚合物的组成和排序，是有机电子学发展的一个关键方面。在这里，在材料开发的每个阶段都描述了 π 共轭编程，强调了每种编程模式之间的联系。共价编程是在聚合物合成过程中进行的，因此可以构建复杂的结构，通过控制聚合物取向、π-π 相互作用和形态长度尺度来指导聚合物组装。随着聚合物在溶液中溶解、聚集、结晶或反应，溶液编程在溶剂化状态下进行。固态编程发生在固态中，并受聚合物结晶、域分离或凝胶化的控制。研究了跨这些阶段的编程的最新进展，突出了 π 共轭聚合物独有的依赖顺序的特征和组装技术。这应该作为描述引导 π 共轭聚合物组装以控制排序、结构和功能的多种方式的指南，从而促进有机电子学的进一步发展。研究了跨这些阶段的编程的最新进展，突出了 π 共轭聚合物独有的依赖顺序的特征和组装技术。这应该作为描述引导 π 共轭聚合物组装以控制排序、结构和功能的多种方式的指南，从而促进有机电子学的进一步发展。研究了跨这些阶段的编程的最新进展，突出了 π 共轭聚合物独有的依赖顺序的特征和组装技术。这应该作为描述引导 π 共轭聚合物组装以控制排序、结构和功能的多种方式的指南，从而促进有机电子学的进一步发展。

Programmable Assembly of π-Conjugated Polymers

π-Conjugated polymers have numerous applications due to their advantageous optoelectronic and mechanical properties. These properties depend intrinsically on polymer ordering, including crystallinity, orientation, morphology, domain size, and π–π interactions. Programming, or deliberately controlling the composition and ordering of π-conjugated polymers by well-defined inputs, is a key facet in the development of organic electronics. Here, π-conjugated programming is described at each stage of material development, stressing the links between each programming mode. Covalent programming is performed during polymer synthesis such that complex architectures can be constructed, which direct polymer assembly by governing polymer orientation, π–π interactions, and morphological length-scales. Solution programming is performed in a solvated state as polymers dissolve, aggregate, crystallize, or react in solution. Solid-state programming occurs in the solid state and is governed by polymer crystallization, domain segregation, or gelation. Recent progress in programming across these stages is examined, highlighting order-dependent features and assembly techniques that are unique to π-conjugated polymers. This should serve as a guide for delineating the many ways of directing π-conjugated polymer assembly to control ordering, structure, and function, enabling the further development of organic electronics.
