Recently, both experimental and theoretical advances have demonstrated that two-dimensional conjugated metal–organic frameworks (2D-cMOFs) exhibit interesting electronic and magnetic properties, such as high conductivity and ferromagnetism. Theoretical studies have predicted that exotic quantum states, including topological insulating states and superconductivity, emerge in some 2D-MOFs. The high design tunability of MOFs’ structure and composition provides great opportunities to realize these structures. However, most conventional synthesis methods yield multilayer structures of the 2D-cMOFs, in which the predicted exotic quantum phases are often quenched because of interlayer interactions. It is highly desirable to synthesize single-layer cMOFs. On-surface synthesis represents a novel strategy toward this goal. In this Perspective, we discuss the recent developments in on-surface synthesis of 1D- and 2D-cMOFs.
