Polymer single crystals (PSCs) mainly appearing as quasi‐two‐dimensional lamellae and are typically used as model systems to determine polymer crystalline structures. Recent research has demonstrated that they can also be used as nanoscale functional materials. In particular, nanoparticles can be directed to assemble into complex shapes by using in situ or ex situ polymer crystal growth. End‐functionalized polymers can crystallize into 2D nanosheets, which are used to conjugate with complementary nanoparticles, leading to a nanosandwich structure. These nanosandwiches can find interesting applications for catalysis, surface‐enhanced Raman spectroscopy, and nanomotors. Dissolution of the nanosandwich leads to the formation of Janus nanoparticles, providing a unique method for asymmetric nanoparticle synthesis. An overview on these aspects is given in the Review article by C. Y. Li et al. on page 349 ff.
