Organic optoelectronic devices based on conjugated polymers have attracted widespread attention and practical applications have been achieved. Various solution‐processing protocols for depositing conjugated polymeric thin films of organic optoelectronic devices have been developed. As a low‐cost solution‐processing technique, the layer‐by‐layer (LbL) assembly method can be used to fabricate multilayer thin films with a high‐quality surface and controlled thickness. Recent remarkable progress in LbL‐assembled multilayer films for the interface engineering of organic optoelectronic devices has demonstrated their great potential for practical applications in the near future. Here, the application of LbL assembly to the construction of multilayer films is discussed for use in polymer optoelectronic devices, especially polymer light‐emitting diodes (PLEDs) and polymer solar cells (PSCs). A brief introduction to LbL‐assembled multilayer films for the emissive/active layers in PLEDs/PSCs is provided and the limitations of LbL materials are discussed. The comprehensive application of LbL‐assembly techniques and LbL materials in the interface engineering of PLEDs and PSCs is also presented with a supplementary discussion of the working mechanism of LbL materials in PLEDs and PSCs. Finally, perspectives on the LbL‐assembly technique and challenges to its application in future organic optoelectronic devices are presented.
