Exploring methods for assembling functional materials at the molecular level may yield functional expressions derived from the assembly method. This study developed novel switchable molecular assemblies characterized by abrupt, complete phase transitions promoted via hydrogen bonding with a chiral carboxylic acid. These assemblies were prepared by aggregating discrete molecules that are unresponsive to external stimuli. Furthermore, enantiopure hydrogen-bond donor (HBD) molecules provide switchable compounds with cooperative and abrupt phase transitions, whereas the racemic mixture of the HBD provides a hydrogen-bonded one-dimensional compound with a broad and incomplete phase transition when structural disordering is observed. This study presents a novel strategy for observing metal-to-metal electron-transfer-coupled spin transitions via hydrogen-bond formation.

使用手性氢键供给单元组装最小的普鲁士蓝类似物以实现完全相变

探索在分子水平上组装功能材料的方法可能会产生源自组装方法的功能表达式。这项研究开发了新型可转换分子组件，其特征是通过与手性羧酸的氢键促进突然、完全的相变。这些组件是通过聚集对外部刺激无反应的离散分子来制备的。此外，对映体纯氢键供体 (HBD) 分子提供具有协作和突然相变的可转换化合物，而 HBD 的外消旋混合物提供氢键一维化合物，当观察到结构无序时，该化合物具有广泛且不完全的相变。这项研究提出了一种通过氢键形成观察金属间电子转移耦合自旋跃迁的新策略。
