“…Ligands based on trinaphthalene 35 or truxene 36 yield larger pore size compared to those based on benzene 37 – 40 or triphenylene. 41 – 43 Additionally, phthalocyanine 44 – 46 and dibenzo[ g,p ]chrysene 33 cores with D 2 symmetry, as well as phenanthrotriphenylene-based ligands 47 with D 2h symmetry, typically adopt tetragonal or rhombic lattices. Despite the promising advancements in 2D c -MOFs, the reported organic linkers are limited in the mentioned types featuring various ortho -substituted sites.…”

Two-dimensional conductive metal–organic frameworks (2D c-MOFs) have attracted research attention, benefitting from their unique properties such as superior electronic conductivity, designable topologies, and well-defined catalytic/redox-active sites. These advantages enable 2D c-MOFs as promising candidates in electrochemical energy applications, including supercapacitors, batteries and electrocatalysts. This mini-review mainly highlights recent advancements of 2D c-MOFs in the utilization for electrochemical energy storage, as well as the forward-looking perspective on the future prospects of 2D c-MOFs in the field of electrochemical energy.Table of content:1 Introduction2 Design Principles of 2D c-MOFs3 Synthesis of 2D c-MOFs4 2D c-MOFs for Electrochemical Energy Storage4.1 Supercapacitors4.2 Metallic Batteries4.2.1 Lithium-Ion Batteries4.2.2 Sodium-Ion Batteries4.2.3 Zinc-Ion Batteries4.2.4 Sodium–Iodine Batteries4.2.5 Lithium–Sulfur Batteries4.2.6 Potassium-Ion Batteries5 2D c-MOFs for Electrochemical Energy Conversion6 Conclusions and Outlook

“…The generality of this anodic strategy was confirmed by the successful synthesis of oriented films of other Mcatecholate MOFs constructed from different ligands and metal ions, including 2D Zn 3 (HHTP) 2 , 60 2D Co 3 (HHTP) 2 , 40 3D YbHHTP, 61 and 2D Cu 2 TBA (TBA = octahydroxyl tetrabenzoanthracene). 62,63 With advantages such as short reaction time, large-range tuning of thickness, and no limitation to ligands with low sublimation/boiling points, this electrochemical strategy is complementary to Langmuir− Blodgett deposition, CVD, and other methods for producing oriented MOF films. 64,65 ■…”

Effective control over the crystallization of metal–organic framework (MOF) films is of great importance not only for the performance study and optimization in related applications but also for the fundamental understanding of the involved reticular chemistry. Featuring many technological advantages, electrochemical synthesis has been extensively reported for many MOF materials but is still challenged by the production of dense oriented films with a large-range tuning of thickness. Here, we report a ligand-oxidation-based anodic strategy capable of synthesizing oriented films of two-dimensional (2D) and three-dimensional (3D) conductive M-catecholate MOFs (2D Cu3(HHTP)2, 2D Zn3(HHTP)2, 2D Co3(HHTP)2, 3D YbHHTP, and 2D Cu2TBA) with tunable thicknesses up to tens of micrometers on commonly used electrodes. This anodic strategy relies on the oxidation of redox-active catechol ligands and follows a stepwise electrochemical-chemical reaction mechanism to achieve effective control over crystallizing M-catecholate MOFs into films oriented in the [001] direction. Benefiting from the electrically conductive nature, Cu3(HHTP)2 films could be thickened at a steady rate (17.4 nm·min–1) from ∼90 nm to 10.7 μm via a growth mechanism differing from those adopted in previous electrochemical synthesis of dense MOF films with limited thickness due to the self-inhibition effect. This anodic synthesis could be further combined with a templating strategy to fabricate not only films with well-defined 2D features in sizes from micrometers to millimeters but also high aspect ratio mesostructures, such as nanorods, of Cu3(HHTP)2.
