Long‐range orientational order in polymers, especially in conjugated polymers (CPs), is of significance in soft matter: from in‐depth understanding of their intrinsic states to fabrication of high‐performance CP‐based devices. However, this field is under‐explored due to lack of approaches to realizing such long‐range order in CPs. Here a universal rule for the synthesis of highly oriented CPs is presented: in a very stable environment with controllable growth rate and size. In order to verify this rule, the growth of highly oriented PPy is realized within the semi‐closed micropores of a graphene foam using a solventless polymerization method at low temperature. These findings provide directions for the construction of ordered CPs. Further explorations of the physical/chemical properties and high‐performance CP‐based device fabrication are anticipated.

通过无溶剂聚合策略实现共轭聚合物的远距离取向顺序

聚合物，特别是共轭聚合物（CP）中的长距离取向顺序在软物质中具有重要意义：从对它们的内在状态的深入了解到高性能基于CP的器件的制造。但是，由于缺乏在CP中实现这种远距离顺序的方法，因此该领域的研究不足。这里提出了合成高度定向CP的通用规则：在非常稳定的环境中，可控制的生长速率和尺寸。为了验证该规则，在低温下使用无溶剂聚合方法在石墨烯泡沫的半封闭微孔内实现了高度定向的PPy的生长。这些发现为构建订购的CP提供了指导。
