Derivatization of porous molecular network formed by 1,3,5-tris (10-carboxydecyloxy) benzene (TCDB) via hydrogen bond interaction is demonstrated in this work. With the introduction of 4,4'-bipyridyl (Bpy) the TCDB network is observed to form a heteromolecular cluster, TCDB6-Bpy6, on highly oriented pyrolytic graphite (HOPG) surface under ambient conditions using scanning tunneling microscopy (STM). The derivatized network is further observed to accommodate single guest species such as coronene to form a well-ordered ternary two-dimensional (2D) structure.
本工作展示了通过氢键相互作用对由1,3,5-三（10-羧基癸氧基）苯（TCDB）形成的多孔分子网络进行衍生化。通过引入4,4'-联吡啶（Bpy），利用扫描隧道显微镜（STM）在环境条件下观察到TCDB网络在高度取向热解石墨（HOPG）表面形成异分子簇TCDB6-Bpy6。进一步观察到衍生化网络能够容纳诸如并五苯等单个客体物种，形成有序的三元二维（2D）结构。
