The prediction of two-dimensional mol. self-assembly structures has always been a problem to be solved. The mols. with meta-dicarboxyl groups can self-assemble into a specific hexagonal cavity, which has an important influence on the prediction of mol. self-assembly structures and the application of functional mols. with meta-dicarboxyl groups. Two kinds of mols. with four pairs of meta-dicarboxyl groups, 1,3,6,8-tetrakis(3,5-isophthalic acid)pyrene (H8TIAPy) and 4¡ä,4¡ä¡ä¡ä,4¡ä¡ä¡ä¡ä¡ä,4¡ä¡ä¡ä¡ä¡ä¡ä¡ä-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1¡ä-biphenyl]-3,5-dicarboxylic acid)) (H8ETTB) mols. were chosen to observe the self-assembly behavior at the heptanoic acid/highly oriented pyrolytic graphite (HA/HOPG) interface. H8TIAPy mols. self-assembled into well-ordered quadrilateral structures and could be regulated into kagome networks with hexagonal pores by coronene (COR) mols. H8ETTB mols. self-assembled into lamellar structures and transformed into acid-COR-acid-COR co-assembled structures at low concentration of COR solution and acid-COR dimer-acid-COR dimer co-assembled structures at high concentration of COR solution The reason that H8ETTB mols. could not be regulated into hexagonal porous architecture was attributed to the steric hindrance by the similar length and width of H8ETTB mols. The H8ETTB templates had stronger adsorption for COR than that of hexaphenylbenzene (HPB), regardless of the order of mol. introduction.
