报告摘要：In this talk I will discuss our recent efforts of synthesizing and investigating the electronic properties of novel low-dimensional organic materials under ultra-high vacuum (UHV) conditions using low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) and atomic force microscope (AFM) complemented by density-functional theory (DFT) calculations: 1) We report the growth of an ultraflat biphenylene network with periodically arranged four-, six-, and eight-membered rings of sp2-hybridized carbon atoms through an on-surface interpolymer dehydrofluorination (HF-zipping) reaction. STS reveals that it is metallic rather than a dielectric. 2) We demonstrate a successful synthesis of Cu-dicyanoanthracene (DCA) 2D MOF on the weakly interacting 2D materials (graphene/Ir(111) and NbSe2) . The ordered DCA3Cu2 network shows a structure combining a honeycomb lattice of Cu atoms with a kagome lattice of DCA molecules. We confirm that a kagome band structure is formed in the 2D MOF. We expect that a similar strategy can be applied to the development of emerging quantum materials.
