电子和光电器件通常需要多功能特性与导电性相结合，这是单一分子无法实现的。调节导电共聚物的链长、形状和物理化学特性的能力为需要独特和工程化的光学、电学或光电特性的广泛科学领域提供了实质性益处。虽然已经努力开发合成路线，以实现这样的有前途的共聚物，理解的合成方法的过程-结构-性能的关系需要进一步提高。此外，由于传统的方法往往局限于实现无针孔，大面积覆盖，和保形涂层的共聚物膜的厚度可控性，非常规的合成策略，以解决这些问题需要建立。这篇透视文章旨在通过提供共聚物的定义，聚合机理以及传统和新兴合成方法与反应参数和调整的物理性能的比较来增强对功能共聚物的工艺-结构-性能关系的认识。同时，展示了所需共聚物在电子，光学和传感器件中的实际应用。最后，对下一代器件应用的独特共聚物的进一步发展的途径进行了讨论。
Electronic and optoelectronic devices often require multifunctional properties combined with conductivity that are not achieved from a single species of molecules. The capability to tune chain length, shape, and physicochemical characteristics of conductive copolymers provides substantial benefits for a wide range of scientific areas that require unique and engineered optical, electrical, or optoelectronic properties. Although efforts have been made to develop synthetic routes to realize such promising copolymers, an understanding of the process–structure–property relationship of the synthesis methods needs to be further enhanced. In addition, since traditional methods are often limited to achieving pinhole-free, large-area coverage, and conformal coating of copolymer films with thickness controllability, unconventional synthetic strategies to address these issues need to be established. This Perspective article intends to enhance knowledge on the process–structure–property relationship of functional copolymers by providing the definition of copolymers, polymerization mechanisms, and a comparison of traditional and emerging synthetic methods with reaction parameters and tuned physical properties. In parallel, practical applications featuring the desired copolymers in electronic, optical, and sensing devices are showcased. Last, a pathway toward further advancement of unique copolymers for next-generation device applications is discussed.
