二维多孔网络由于可以将功能单元作为客体分子以空间有序的方式排列而引起了人们的极大关注。在这项工作中，一种新的分子混合网络的两种类型的空腔的制作。几种客体分子，如晕苯，铜（II）酞菁（CuPc），苯并菲，庚酸和富勒烯分子，可以固定到该模板。可以观察到位点和大小选择性效应。此外，我们还制作了有趣的二维晶体结构与复杂的四个组成部分的结构在液-固界面，通过扫描隧道显微镜（STM）的调查。目前的研究结果提供了一种方便的方法，形成更复杂和功能化的表面纳米粒子，这可以有利于研究由界面处的几种组分组成的单层内的主客体组装行为。
2D porous networks have attracted great attention as they can be used to immobilize functional units as guest molecules in a spatially ordered arrangement. In this work, a novel molecular hybrid network with two kinds of cavities was fabricated. Several kinds of guest molecules, such as coronene, copper(II) phthalocyanine (CuPc), triphenylene, heptanoic acid and fullerene molecules, can be immobilized into this template. Site- and size-selective effects can be observed. Furthermore, we have also fabricated interesting 2D crystal architecture with complex four-component structure at the liquid-solid interface, following investigation by scanning tunnelling microscopy (STM). The current findings provide a convenient approach towards the formation of more complex and functionalized surface nanopatterns, which can benefit the study of host-guest assembly behaviour within a monolayer composed by several components at interfaces.
