Kagome lattices have garnered significant attention due to their promising applications in catalysis,electronics,and magnetics.Alt-hough many efforts have been paid to the design and synthesis of Kagome lattices,there is a limited focus on constructing this lattice by multiple interaction forces.In this work,we employ 2,7-dibromo-carbazole as precursors to successfully fabricate the two-dimen-sional self-assembly Kagome lattices stabled by multiple interaction forces on Au(111)substrate.Using low-temperature scanning tunneling microscopy,non-contact atomic force microscopy and density functional theory calculation,we visualize and identify the four interaction forces within Kagome lattices:Au—N coordination bonds,Au—H hydrogen bonds,Br—Br halogen bonds,and Br—H hydrogen bonds,respectively.This study provides a basic understanding for designing and constructing more complex Kagome lattices.
