Precisely tuned functional coordination nanosheet exhibits competent catalytic activity for HER, accompany with drastic electronic property switching by redox treatment.

Synthesis of Bimetallic Conductive 2D Metal–Organic Framework (CoxNiy‐CAT) and Its Mass Production: Enhanced Electrochemical Oxygen Reduction Activity

“…And so, many MOFs are used indirectly in electrocatalytic applications as precursor materials for the production of porous carbon‐based ORR catalysts through the pyrolysis . Fortunately, some conductive MOFs have recently been developed, which can be directly used in electrocatalytic applications.…”

Multielectron‐Transfer‐based Rechargeable Energy Storage of Two‐Dimensional Coordination Frameworks with Non‐Innocent Ligands

“…This unusual behavior might be due to the altered electric conductivity at the respective charge states. In our previous work, the other types of 2D framework were indeed found to show electric conductivity lowered by chemical reduction . However, detailed analysis is out of the scope of this report and will be investigated in the future.…”

Liquid-interface-assisted synthesis of covalent-organic and metal-organic two-dimensional crystalline polymers

“…On the other hand, fully conjugated 2D MOFs have been emerging with the realization of high electrical conductivity (10 −3~1 0 3 S/cm) since the report about Cu/Ni-catecholates (H4) by Yaghi et al in 2012. 45 Currently, fully conjugated 2D MOFs have been synthesized by linking N, O, or S ortho-disubstituted benzene (H1-H3) 22,41,46 or triphenylene (H4-H6) 24,40,42 ligands with square planar linkages, such as metal-bis(diimino)/-bis(dihydroxy)/bis(dithiolene), as well as their hybrids (Fig. 2h), and are featured with hexagonal lattices, layered structures and full π-d conjugation in 2D planes.…”

“…One can expect that covalent-organic and metal-organic 2DCPs with large area, highly ordered opened-porous structures, ultra-thin and free-standing feature, and integration of abundant functional units will open up a wide range of applications in optics, 35 electronics, 22,25,34,38,41,42,45 sensing, 44,47 separation, 18,37 energy storage, and conversion. 24,40,43,46,[48][49][50] Nevertheless, the superior performances in these applications highly rely on structural control of the 2DCPs at the atomic and molecular level. Thus, the reliable and fundamental structure-property relationship should be addressed, which will flourish the development of 2DCPs via liquid-interface assisted synthesis in the future.…”
