Here, we report a unique mesoporous ionic solid () generated from a cationic Au Ag Cu dodecanuclear complex with d-penicillamine depending on the homochirality and crystallization conditions. crystallizes in the cubic space group of 432 with an extremely large cell volume of 2 171 340 Å, containing 272 Au Ag Cu complex cations in the unit cell. In , the complex cations are connected to each other through CH⋯π interactions in a zeotype framework, the topology of which is the same as that of the metal-organic framework in MIL-101, with similar but much larger two types of polyhedral pores with internal diameters of 38.2 Å and 49.7 Å, which are occupied by counter-anions and water molecules. Due to the cationic nature of the framework, undergoes quick, specific exchanges of counter-anions while retaining its single crystallinity. This study realized the creation of a non-covalent mesoporous framework from a single complex salt, providing a conceptual advance in solid chemistry and material science.
在此，我们报道了一种独特的介孔离子固体（），它由一种阳离子型金银铜十二核配合物与d-青霉胺反应生成，具体取决于同手性和结晶条件。该固体结晶于立方空间群432，晶胞体积极大，为2171340 ų，单位晶胞中含有272个金银铜配合物阳离子。在该固体中，配合物阳离子在类沸石骨架中通过CH⋯π相互作用彼此相连，其拓扑结构与MIL-101中的金属有机骨架相同，具有两种类似但尺寸大得多的多面体孔，内径分别为38.2 Å和49.7 Å，孔中填充有抗衡阴离子和水分子。由于骨架的阳离子性质，该固体在保持单晶性的同时能快速、特异性地进行抗衡阴离子交换。本研究实现了从单一复合盐制备非共价介孔骨架，为固体化学和材料科学提供了概念上的进展。
