Organic cocrystal engineering refers to two or more organic molecules stoichiometrically combined and held together by noncovalent intermolecular interactions, which differs from standard chemical synthesis involving covalent bond breakage and formation. Organic cocrystals have unique properties and offer a new strategy for creating enhanced organics. First, however, some key questions need to be addressed: How do diverse monomers affect the intermolecular interaction kinetics during cocrystallization? How do the intermolecular forces in cocrystals affect cocrystal functions? In this Perspective, the definition and advantages of organic cocrystal engineering, specifically in the construction of a reliable intermolecular interaction–stacking structure–performance relationship, are outlined. Additionally, recent developments in the field and the questions above are discussed. Finally, a brief conclusion and some hints on likely future developments are provided.

通过有机共晶工程创造超越化学键合成的有机功能材料

有机共晶工程是指两个或多个有机分子通过非共价分子间相互作用以化学计量方式结合并保持在一起，这不同于涉及共价键断裂和形成的标准化学合成。有机共晶体具有独特的特性，并为创造增强型有机物提供了新的策略。然而，首先需要解决一些关键问题：不同的单体如何影响共结晶过程中的分子间相互作用动力学？共晶中的分子间作用力如何影响共晶功能？在这个观点中，概述了有机共晶工程的定义和优势，特别是在构建可靠的分子间相互作用-堆叠结构-性能关系方面。此外，讨论了该领域的最新发展和上述问题。最后，提供了一个简短的结论和一些关于未来可能发展的提示。
