The monolayer self-assembled porous supramolecular networks of p-terphenyl-3,5,3′′,5′′-tetra-carboxylic acid (TPTC) that stabilized by intermolecular hydrogen bonding between four carboxyl groups at nonanoic acid/graphite interface were constructed. Scanning tunneling microscopy (STM) demonstrates that the guest molecules coronene (COR) adsorption in the pores of TPTC monolayer network. Furthermore, TPTC molecules can form the bilayer supramolecular framework and the trapping of COR guest molecules in both layers.

通过扫描隧道显微镜在液/固界面上构建主客体超分子双层网络

构建了对-三苯基-3,5,3'，5''-四羧酸（TPTC）的单层自组装多孔超分子网络，该网络通过壬酸/石墨界面上四个羧基之间的分子间氢键稳定化。扫描隧道显微镜（STM）证明客体分子molecules（COR）吸附在TPTC单层网络的孔中。此外，TPTC分子可以形成双层超分子框架，并且COR客体分子会在两层中被捕获。
