The self-assembly of a tetrathiafulvalene (TTF) derivative (EDTTF) and a 1,3,5-tris(10-carboxydecyloxy)-benzene (TCDB) heterobilayer nanostructure at the 1-phenyloctane/HOPG interface under ambient conditions has been studied by scanning tunneling microscopy (STM). EDTTF and TCDB could co-assemble into a brand new hexagonal network with one of the largest nano-cavities. Finally, the nanoporous network would transform into a more stable linear structure. Density functional theory (DFT) calculations have been performed to reveal the formation mechanism.
通过扫描隧道显微镜（STM）研究了在环境条件下，四硫富瓦烯（TTF）衍生物（EDTTF）和1,3,5-三（10-羧基癸氧基）苯（TCDB）异质双层纳米结构在1-苯基辛烷/高定向热解石墨（HOPG）界面上的自组装。EDTTF和TCDB能够共同组装成一种具有最大纳米腔之一的全新六边形网络。最后，纳米多孔网络会转变为一种更稳定的线性结构。已进行密度泛函理论（DFT）计算以揭示其形成机制。
