Abstract
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.
