金属配位的Kagome晶格在Au(111)面上由自由基四吡啶基卟啉分子自组装而成。表面提供的Au原子以2重线性配位的方式配位相邻的卟啉的吡啶基官能团。通过比较同一分子在不同表面(金、银、铜)上的自组装，可以看出表面的结构和化学特性在决定超分子附着层结构中起着重要作用。
A two-dimensional network of metal-coordinated Kagome lattice has been self-assembled by free-base tetrapyridyl porphyrin molecules on a Au(111) surface. Au ad-atoms offered by the surface coordinate the pyridyl functions of the neighboring porphyrins in a 2-fold linear coordination. Comparison of the self-assemblies of the same molecules on various surfaces (Au, Ag, and Cu) underlines the fact that both structural and chemical characteristics of surfaces play important roles in determining the supramolecular adlayer structures.
