The increasingly diverse and advanced applications of materials necessitate new strategies that can combine widely disparate components to provide unique properties and functions. However, the combination of structurally and functionally diverse organic compounds remains challenging owing to structural mismatches. Herein, we demonstrate the engineering of organic molecule-ionic solids (OMISs) using strong ionic interactions to overcome the structural obstacles to inventing new functional materials. We designed a series of multiply charged organic cations and anions having organic skeletons that are mismatched in size, shape, symmetry, flexibility, and characteristics. In water, they formed ion-pair complexes with stoichiometric charges. Structural analysis confirmed the molecular-level combination of ion pairs mainly through ionic interactions. Therefore, the OMISs gained novel and/or enhanced functions different from those of their constituents. The universality of this work demonstrates that myriad new molecular materials can be discovered through this combinatorial approach owing to the diversity of organic compounds.

通过吸引相互作用形成的结构不匹配离子对的有机分子离子固体

材料日益多样化和先进的应用需要新的策略，这些策略可以结合广泛不同的组件以提供独特的特性和功能。然而，由于结构不匹配，结构和功能多样的有机化合物的组合仍然具有挑战性。在此，我们展示了有机分子-离子固体 (OMIS) 的工程利用强离子相互作用来克服发明新功能材料的结构障碍。我们设计了一系列多电荷有机阳离子和阴离子，它们的有机骨架在尺寸、形状、对称性、柔韧性和特性上不匹配。在水中，它们形成具有化学计量电荷的离子对复合物。结构分析主要通过离子相互作用证实了离子对的分子水平组合。因此，OMIS 获得了与其成分不同的新颖和/或增强的功能。这项工作的普遍性表明，由于有机化合物的多样性，可以通过这种组合方法发现无数新的分子材料。
