Abstract
Abstract 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.
