In the present investigation, we reported the fabrication of a chicken-wire porous 2D network formed by triphenylene-2,6,10-tricarboxylic acid (H3TTCA) at the liquid-solid interface. When coronene (COR) molecules were added into the system, the H3TTCA honey-comb network was broken and the reconstructed structures of the H3TTCA/COR host-guest systems were subsequently formed. Scanning tunneling microscopic (STM) measurements and density function theory (DFT) calculations were utilized to reveal the structural variety in the co-assembly of H3TTCA/COR controlled by the solution concentration at 1-heptanoic acid/HOPG interface.
在本研究中，我们报道了在液-固界面由三亚苯基-2,6,10-三羧酸（H3TTCA）形成的鸡笼状多孔二维网络的制备。当将晕苯（COR）分子加入该体系时，H3TTCA蜂窝状网络被破坏，随后形成了H3TTCA/COR主客体体系的重构结构。利用扫描隧道显微镜（STM）测量和密度泛函理论（DFT）计算来揭示在1-庚酸/HOPG界面处由溶液浓度控制的H3TTCA/COR共组装中的结构多样性。
