在本研究中，我们报道了由三亚苯-2,6,10-三羧酸（H3TTCA）在液-固界面形成的鸡丝多孔二维网络的制造。当晕苯（COR）分子添加到系统中时，H3TTCA蜂窝网络被破坏，随后形成了H3TTCA/COR主客体系统的重建结构。利用扫描隧道显微镜 (STM) 测量和密度函数理论 (DFT) 计算揭示了 H3TTCA/COR 共组装中受 1-庚酸/HOPG 界面溶液浓度控制的结构变化。
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.
