“…Given all that, the synthesis of 2D c-MOFs as single-crystals or single-domain monolayers is urgently required for future advancement. 241 Over eight years of development, despite many open questions and the huge gap between this stage and the commercialization of MOFtronics, 2D c-MOFs have exhibited extraordinary electrical conductivity up to 2500 S cm À1 , band-like transport with mobility reaching B220 cm 2 V À1 s À1 and tailorable band gaps that particularly encourages further studies. Furthermore, 2D c-MOFs feature many other unique properties of tunable porosity, redox and photoactivity, magnetic ordering and high stability, which make them appealing advanced electronic materials for the next-generation of electronic devices.…”

“…The types and ratios of central metal ions and ligands can be adjusted to directly control the structure and properties of conductive MOFs. In particular, among the conductive MOFs, two‐dimensional (2D) conductive MOFs are one of the hotspots studies in recent years [87–90] . Table 2 shows some detailed characteristics values of conductive MOFs as electrode materials in the reported supercapacitors.…”

Supercapacitors possess important prospects in power supply, owing to the characteristics of fast charging/discharging and long cycling life. As emerging materials, metal-organic frameworks (MOFs) are the cutting-edge electrode active materials for supercapacitors due to their good conductivity, tunable pore structure, as well as diverse composition. In this Minireview, we summarize the recent progress in MOF electrodes for supercapacitors. We focus on the synthesis of intrinsically conductive MOFs constructed from different organic linkers and adjustable metal ions, and the preparation of conductive MOF composites hybridized with conducting materials (conducting polymers and carbons). Following the discussion of both different types of conductive MOFs and their composites in supercapacitors, the challenges, and opportunities of conductive MOF electrodes for supercapacitors are further prospected at the end of this contribution, which would provide some valuable insights in facilitating the use of MOF materials in energy-storage applications.

“…When designing new experimental materials, X‐ray crystallography is typically adopted to construct such a structural model. While single‐crystal X‐ray diffraction (SCXRD) measurements allow for the direct atomic‐level determination of a material's bulk structure, [19] it is notoriously difficult to obtain large single crystals for most porous materials such as MOFs and COFs and one usually resorts to powder X‐ray diffraction (PXRD) measurements [20] or electron crystallography [21, 22] . During a PXRD measurement, however, the 3D reciprocal space is non‐injectively projected onto a 1D Bragg angle, making the determination of the true structural model impossible without prior information about the structural model.…”

Structurally characterizing new materials is tremendously challenging,especially when single crystal structures are hardly available which is often the case for covalent organic frameworks.Y et, knowledge of the atomic structure is key to establish structure-function relations and enable functional material design. Herein, an ew protocol is proposed to unambiguously predict the structure of poorly crystalline materials through al ikelihood ordering based on the X-ray diffraction (XRD) pattern. Keyo fthep rocedure is the broad set of structures generated from al imited number of building blocks and topologies,w hichi ss ubmitted to operando structural characterization. The dynamic averaging in the latter accounts for the operando conditions and inherent temporal character of experimental measurements,y ielding unparalleled agreement with experimental powder XRD patterns.T he proposed concept can hence unquestionably identify the structure of experimentally synthesized materials, ac rucial step to design next generation functional materials.
