On-surface synthesis of metal–organic frameworks: the critical role of the reaction conditions

Abstract

We have grown two different metal-organic frameworks with either honeycomb or Kagome structure on Cu(111) using para-aminophenol molecules and native surface adatoms. Although structurally different, both frameworks are made up...

Surface-supported metal−organic frameworks with geometric topological diversity via scanning tunneling microscopy

“…The network structure formed by para -aminophenol molecules on Cu(111) surface could be adjusted to Kagome or honeycomb lattice through a kinetic or thermodynamically controlled reaction ( Figures 8 A and 8B). 82 The optimized network structure revealed that coordination bonds formed between N/O atoms and Cu atoms dominated the establishment of SMOF ( Figures 8 C and 8D). The oxidation process of precursor molecules on the surface was completely dependent on the final temperature (thermodynamics).…”

Construction of Two-Dimensional Organometallic Coordination Networks with Both Organic Kagome and Semiregular Metal Lattices on Au(111)

“…Crucially, 2D MONs having heterogeneous coordination nodes (HCNs) are expected to exhibit excellent performance in many fields such as catalysis − and optoelectronics because the heterogeneous nature of metal coordination nodes may induce dipole and spin polarization as a result of the locally unbalanced electron distribution. − For example, Lopez et al synthesized a Kagome MON composed of N 2 -Cu-O 2 nodes on Cu(111), and Abel et al constructed a 2D MON with O 3 -Fe-N nodes on Ag(111) . In contrast, Wu et al reported a binodal 2D organometallic network composed of both CC–Ag–CC and CC–Ag–phenyl nodes, whose synthesis involves a dissymmetric reaction of a terminal alkyne and bromobenzene on Ag(111) .…”
