A flexible and versatile method to fabricate two-dimensional metal-organic coordination networks (MOCNs) by bottom-up self-assembly is described. 2D crystalline layers were formed at the air-water interface, coordinated by ions from the liquid phase, and transferred onto a solid substrate with their crystallinity preserved. By using an inherently three-dimensional amphiphile, namely 25,26,27,28-tetrapropoxycalix[4]arene-5,11,17,23-tetracarboxylic acid, and a copper metal node, large and monocrystalline dendritic MOCN domains were formed. The method described allows for the fabrication of monolayers of tunable crystallinity on liquid and solid substrates. It can be applied to a large range of differently functionalized organic building blocks, also beyond macrocycles, which can be interconnected by diverse metal nodes.
描述了一种通过自下而上的自组装来制备二维金属有机配位网络（MOCN）的灵活通用方法。在空气-水界面形成二维结晶层，由液相中的离子配位，并在保持其结晶度的情况下转移到固体基底上。通过使用一种固有三维的两亲物，即 25,26,27,28-四丙氧基杯[4]芳烃-5,11,17,23-四羧酸，和一个铜金属节点，形成了大的单晶树枝状 MOCN 畴。所描述的方法允许在液体和固体基底上制备具有可调结晶度的单层。它可以应用于各种不同功能化的有机构筑块，也可以超越大环，通过各种金属节点进行相互连接。
