The selective assembly of carboxyphenyl substituted porphyrins on the Au (111) surface has been studied using scanning tunneling microscopy. We find that conformational isomers of the porphyrins are induced upon adsorption and are selectively assembled into hydrogen-bonded supramolecular clusters or wires on the surface. The conformation selective assembly is attributed to the coplanar intermolecular interactions between hydrogen-bonded carboxyphenyl groups.
利用扫描隧道显微镜研究了羧基苯基取代卟啉在金(111)表面的选择性组装。我们发现,卟啉的构象异构体在吸附时被诱导,并在表面选择性地组装成氢键超分子簇或线。构象选择性组装归因于氢键羧基苯基之间的共面分子间相互作用。
