“…[9][10] The development for electrically conducting MOFs is an area of vigorous research. [11][12][13][14][15][16][17] For example, Kobayashi and co-workers reported a micro-porous framework, Cu[Ni(pdt) 2 ] (pdt 2-= pyrazine-2,3-dithiolate), that shows electrical conductivity, doping, and redox behavior. 12 Gándara et al reported a family of porous metal-triazolate MOFs, one of which exhibits good electrical conductivity.…”

The development of metal organic frameworks (MOFs) with high porosity, large surface area, and good electrical properties would offer opportunities for producing functionalized porous materials suitable for energy storage, conversion, and utilization. Realizing these applications remains challenging because of the limited numbers of electrically conductive porous MOFs that are known. We apply density functional theory (DFT) to assess a large number of potentially electrically conductive MOFs generated by infiltrating known materials with conjugated and redox-active 7,7,8,8-tetracyanquinododimethane (TCNQ) molecules. DFT results demonstrate that TCNQ coordinating with dimeric Cu paddlewheels can create molecular chains in a variety of MOFs. Several of these materials feature the formation of multiple dimensional conducting chains, making the materials promising for electrical conductivity.

“…Lu and co-workers have constructed 3D MOF nanostructures of three different MOFs (HKUST-1, Zn 2 (BDC) 2 DABCO, and MIL-68) on the layers of conducting polyaniline substrates deposited on Pt electrodes . The obtained composite HKUST-1/polyaniline/Pt ( 82 ) shows high porosity and large enhancement of electrical conductivity to 0.125 S cm –1 (four-probe on thin films) upon I 2 adsorption, while the HKUST-1 is itself insulating in nature.…”

Metal−organic frameworks (MOFs), formed by the combination of both inorganic and organic components, have attracted special attention for their tunable porous structures, chemical and functional diversities, and enormous applications in gas storage, catalysis, sensing, etc. Recently, electronic applications of MOFs like electrocatalysis, supercapacitors, batteries, electrochemical sensing, etc., have become a major research topic in MOF chemistry. However, the low electrical conductivity of most MOFs represents a major handicap in the development of these emerging applications. To overcome these limitations, different strategies have been developed to enhance electrical conductivity of MOFs for their implementation in electronic devices. In this review, we outline all these strategies employed to increase the electronic conduction in both intrinsically (frameworkmodulated) and extrinsically (guests-modulated) conducting MOFs.

“…[ 41,75,147,148 ] In 2014, Lu et al provided a strategy of fabricating 3D microporous conductive polymer by integrating MOF thin film with conductive substrate. [ 149 ] The obtained microporous network showed high surface areas and well‐defined uniform micropores as well as high conductivity upon I 2 doping. These findings offered a feasible way to construct highly porous 3D conductive polymer networks.…”

fabricated. Combined with controlled synthesis, MOF materials are endowed with abundant various of structures, morphologies, and properties. [8-11] In addition, the as-prepared MOFs can be artificially modified via postsynthetic approaches utilizing their available pores and active sites of metal clusters or linkers. [12,13] As a result, not only the number of MOFs is further increased but also many interesting properties, such as high specific surface areas, tailorable pore sizes, modifiable structures, and properties are endowed with MOFs, which make them become potential candidates in storage/separation, catalysis, sensing, etc. [14,15] Another important application of MOFs is that they can act as conductive materials for electrocatalysis, sensing, and energy conversion, etc. [16-19] The existence of quantitative amounts of active metal centers, permanent porosity, and structural rigidity can facilitate surface contact and mass transfer as well as increase catalysis stability, making MOFs as ideal electrocatalysts. [20-22] In addition, they possess high specific surface areas, tunable bandgaps, and good charge transport properties, which extend their applications in sensing and energy storage. [23] Besides, the morphologies and characteristics of MOFs can be artificially modified to form 1D, 2D, or 3D structures via liquid phase selfassembly, physical/chemical exfoliation, layer-by-layer assembly, etc., promoting their applications in electrochemical devices and electronics. [24-26] With further structural design through postsynthesized modification, the performances of MOFs can be largely improved, facilitating their applications as conductive materials. [27-29] However, most MOFs are intrinsically electrically insulated, which seriously hinders their electrochemical applications. [29] The connected rigid metal ions and redox-inactive organic ligands increase the energy barrier for electron transfer, making them as electrical insulators. To overcome the drawbacks of MOFs, many feasible strategies have been adopted to promote the electron transfer in the structures of MOFs. [27,30-32] The high electrical conductivity of MOFs can be realized by integrating the conjugated planes or 1D chains in the structures, which relies on particular structural designs. [33-37] The conductivity of the MOFs can also be increased via doping with guest Metal-organic frameworks (MOFs) have aroused worldwide interest over the last two decades due to their various excellent properties, such as porosity, modifiability, stability, etc. Based on these unique features, they have been widely exploited for applications from electrocatalysis to electrochemical devices. However, most MOFs are inherently insulated due to the lack of free charge carriers and low-energy barriers for charge transfer, which largely restricts their further electrochemical applications. By imparting MOFs with electrical conductivity, their electrochemical process and catalysis efficiency can be effectively improved. Similarly, their applications in sensors, secon...
