Structural reconstruction and spontaneous formation of Fe polynuclears: a self-assembly of Fe–porphyrin coordination chains on Au(111) revealed by scanning tunneling microscopy

“…23,24 Moreover, metal species ranging from transition/alkali metals 14,29,[33][34][35][36][37] to lanthanide metals 38,39 have been used to direct the surface coordination networks whose characteristics are highly determined by the metal species and their chemical states as tuned by both the surrounding ligands and the substrates. Recently, similar to the 3D coordination self-assembly in solution or solids where much interest has been focused on poly-(metallic) nuclear complexes, 40 surface-supported coordination self-assembly based on metal polynuclears as coordination nodes has been exploited. [41][42][43][44][45] The precise control of the catalytic and spintronic/magnetic characteristics of the resulting structures thus can be further tuned through both the number of nuclears and the configuration of the polynuclears (or complexes).…”
