两个固相之间的界面的形成在新材料的开发中具有重要意义，因为材料的机械和电子性能受到扭曲的界面结构的强烈影响，导致与单个相不同的性能。此外，多孔材料的性质，如气体吸附和客体分子容纳，也应该与这种材料的界面结构相关，因为客体分子（吸附物）首先遇到多孔材料的表面。因此，多孔材料对客体分子的亲和力可以通过改变表面结构来调节。[1]多孔配位聚合物（PCP）或金属有机框架（MOF）是一类有趣的结晶多孔材料，因为可以设计其框架拓扑结构和孔径以及孔表面的功能。[2]“后合成方法”的最新进展允许在晶格构建之后改变孔表面功能（在材料的内表面上）。[3]另一方面，PCP外表面的功能化是一个很大的挑战，但它是一种有前途的方法，不仅可以改变多孔性能，而且可以为PCP添加新的功能
The formation of interfaces between two solid phases is of great significance in the development of new materials, because mechanical and electronic properties of materials are strongly influenced by distorted interfacial structures, leading to properties that differ from those of the individual phases. Moreover, properties of porous materials, such as gas sorption and guest-molecule accommodation, should also correlate with the interfacial structure of such materials, because guest molecules (adsorbates) first encounter the surface of the porous materials. Hence, the affinity of porous materials for guest molecules can be tuned by modifying the surface structure.[1]Porous coordination polymers (PCPs), or metal–organic frameworks (MOFs), are an interesting class of crystalline porous materials, as it is possible to design their framework topologies and pore sizes and the functionality of the pore surfaces.[2] Recent progress of the “post-synthetic approach” allows for the pore-surface functionalities (on the inner surfaces of materials) to be altered after the lattice is constructed.[3] On the other hand, functionalization of PCP outer surfaces is a great challenge, but it is a promising methodology not only for modification of the porous properties but also for the addition of a new function to the PCP
