Zusammenfassung:Cocrystal engineering with a noncovalent assembly feature by simple constituent units has inspired great interest and has emerged as an efficient and versatile route to construct functional materials, especially for the fabrication of novel and multifunctional materials, due to the collaborative strategy in the distinct constituent units. Meanwhile, the precise crystal architectures of organic cocrystals, with long‐range order as well as free defects, offer the opportunity to unveil the structure–property and charge‐transfer–property relationships, which are beneficial to provide some general rules in rational design and choice of functional materials. In this regard, an overview of organic cocrystals in terms of assembly, containing the intermolecular interactions and growth methods, two functionality‐related factors including packing structure and charge‐transfer nature, and those advanced and novel functionalities, is presented. An outlook of future research directions and challenges for organic cocrystal is also provided. Organic cocrystals have attracted increasing attention in the area of molecular optoelectronics, and they have provided a collaborative strategy toward functional materials. A discussion on controllable assembly for organic cocrystals is highlighted, and the structure–property and charge‐transfer–property relationships are introduced. Furthermore, advanced and novel functionalities are presented, and an outlook is provided.
