Comprehensive Summary

Kagome lattices have garnered significant attention due to their promising applications in catalysis, electronics, and magnetics. Although 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-dimensional 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.
