多孔物质如金属有机框架（MOF）、共价有机框架（COF）和沸石是用于不同应用的重要材料，并且已经开发了几种方法用于将它们加工成器件结构。将小分子前体溶液加工成相应的多孔结构对于许多应用将是有益的，因为它有助于将活性材料组分结合到相关装置中，从而降低复杂性和成本。在这里，我们报告了一个非平面的鞍形N-杂环稠合金属卟啉形成一个持久的微孔晶体材料直接从溶液中，它可以进行溶剂交换而不会损失微孔。该材料是由一个独特的积累的分子间相互作用，包括π-π堆叠的稠合杂环，在金属卟啉类单位的配位相互作用，和氢键。这种分子间多点相互作用的概念将是未来按需合成多孔材料的分子设计的关键，本文所述化合物的简单实施表明了器件材料合成的巨大潜力。还报道了并入纳米机械传感器阵列的材料的感测特性。
Porous substances such as metal–organic frameworks (MOFs), covalent organic frameworks (COFs) and zeolites are important materials for different applications, and several methods have been developed for their processing into device architectures. Solution processing of small molecule precursors into corresponding porous structures would be beneficial for many applications since it facilitates incorporation of the active material component into relevant devices thus reducing complexity and cost. Here we report that a non-planar saddle-shaped N-heterocycle-fused metallo-porphyrinoid forms a persistently microporous crystalline material directly from solution, which can undergo solvent exchange without loss of microporosity. The material is formed by a unique accumulation of intermolecular interactions involving π–π stacking of the fused heterocycle, coordinative interactions at the metalloporphyrinoid unit, and hydrogen bonding. This intermolecular multipoint interaction concept will be key in the future molecular design for on-demand synthesis of porous materials, and the simple implementation of the compound described here indicates the excellent potential for device materials’ synthesis. Sensing properties of the material incorporated into a nanomechanical sensor array are also reported.
