摘要
有机共晶是一种新型的功能材料,由两种或多种有机分子通过非共价相互作用协同组装形成的多功能晶体。这类材料通过调控供体(D)与受体(A)的分子组成和组装方式,突破单一组分性能限制,展现出多样的堆积方式,具有丰富的分子间相互作用和丰富的功能成分,其物理化学性质可以根据不同的要求进行定制,并呈现出新颖的特性。随着有机共晶在光电材料和药物制剂等领域的突破性应用,其制备方法成为材料研究的核心挑战。如何合理设计和选择有机共晶中的D/A组分,使其具有所需的形貌、尺寸和功能是共晶合成的关键目标。本文总结了有机共晶的制备方法,首先对有机共晶进行介绍,概述了其构建和设计特征,以及有机共晶的性能;随后重点介绍了有机共晶的制备方法,最后展望了有机共晶的发展前景。
Organic cocrystals are a novel class of functional materials formed by the synergistic assembly of two or more organic molecules through non-covalent interactions.By strategically modulating the molecular composition and assembly patterns of donor(D)and acceptor(A)components,these materials transcend the performance limitations of singlecomponent systems,exhibiting diverse stacking modes,abundant intermolecular interactions and versatile functional compositions.Their physicochemical properties can be tailored to meet specific requirements while demonstrating novel characteristics.With groundbreaking applications in optoelectronic materials and pharmaceutical formulations,the preparation methods of organic cocrystals have emerged as a central challenge in materials research.The key objective of cocrystal synthesis lies in the rational design and selection of D/A components to achieve desired morphologies,dimensions,and functionalities.This article summarizes the preparation methods for organic cocrystals,beginning with an introduction to their structural features and design principles,following by an overview of their unique properties.A detailed discussion of synthesis techniques is subsequently presented,concluding with perspectives on future development prospects in this field.
