Abstract
The fabrication of bi-component and three-component supramolecular networks based on hydrogen bonds was investigated by scanning tunnelling microscope (STM). Induced by successively introduced coronene (COR) and 1,3,5-benzenetricarboxylic acid (TMA), the intermolecular interactions between [1,1′-biphenyl]-3,4′,5-tricarboxylicacid (BPTC) were changed, leading to the structural transformation of the lamellar self-assembled nanostructure of BPTC on highly oriented pyrolytic graphite (HOPG). Eventually, the flower-like nanostructure of BPTC/COR and kagomé nanostructure of BPTC/TMA/COR were obtained on HOPG substrates respectively. This investigation of the multicomponent host–guest network could be useful for the construction of novel heterogenous molecular structures.
