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.
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固定在其中而受到了极大的关注。在这项工作中，制备了一种具有两种空腔的新型分子杂化网络。几种客体分子，如并五苯、铜酞菁（CuPc）、三苯、庚酸和富勒烯分子，可以被固定到这个模板中。可以观察到位置和尺寸选择性效应。此外，我们还通过扫描隧道显微镜（STM）研究，在固-液界面上制备了具有复杂四组分结构的有趣二维晶体结构。目前的发现为形成更复杂和功能化的表面纳米图案提供了一种便捷的方法，这将有利于在由几个组件组成的单层内研究主体-客体组装行为。
