Synthesis strategies

Review-level synthesis principles remain separate from primary-study recipes.

Hybridisation with carbon-based materials

Combine 2D conducting MOFs with graphene, CNTs, carbon nanofibres, carbon onions, graphene oxide or carbon-paste electrodes.

Claimed effects: Bridges stacked layers, enhances vertical charge conduction and can improve capacity and rate performance.

Controlling variables: carbon scaffold type · interlayer bridge formation · electrode microstructure · ion-diffusion path length

Representative materials: Ni-MOF/C-CNTs · S@Ni3(HITP)2-CNT · Ni-CAT/CNF

Caveat: Composite performance cannot be attributed to the MOF alone without primary-paper controls.

p003 · Hybridization with carbon-based materials

Loading conducting polymers in MOF voids

Polymerise or load conducting polymers in MOF pores so polymer chains or clusters provide delocalised charge pathways.

Claimed effects: Can increase conductivity by creating electron pathways through the framework while retaining crystalline MOF structure in the cited example.

Controlling variables: monomer uptake · oxidative polymerisation · framework crystallinity retention · host-guest interactions

Representative materials: PPy-loaded fluorescent MOF

Caveat: The review's cited-reference mapping for this example should be checked against the primary paper before using it quantitatively.

p003 · Loading with conducting polymers

Guest and dopant incorporation

Introduce electroactive guest molecules, cations, metal oxides, nanoclusters or redox molecules into MOF voids to create additional charge pathways.

Claimed effects: Can add redox-active sites and new conduction channels, but guest inclusion can reduce or eliminate accessible porosity.

Controlling variables: guest identity · post-synthetic versus in-synthesis loading · pore blockage · redox-active site density

Representative materials: KAUST-7' · TCNQ-doped frameworks · CoSNC derived from PPF-3 nanosheets

Caveat: The review warns that bulky guests can truncate porosity and therefore may trade conductivity for ion accessibility.

p003 · Incorporation of dopants · Fig. 4

Liquid-liquid or air-liquid interfacial thin-film growth

Cast conducting MOFs as crystalline or self-standing thin films at interfaces to enhance continuity, morphology and device relevance.

Claimed effects: Can yield high-conductivity thin films and allow Hall or terahertz measurements of mobility and band-like transport.

Controlling variables: interface chemistry · solvent pair · film continuity · ambient atmosphere · metal and thiol linker selection

Representative materials: Cu-BHT · Fe3(THT)2(NH4)3 · Ag3BHT2

Caveat: Thin-film values are review-reported secondary benchmarks and depend strongly on film morphology and measurement geometry.

p002 · Origin of electrical conductivity in MOFs

Selective linker and metal-node design

Choose planar, conjugated, chelating linkers and compatible metal nodes to generate ordered 2D charge-transport pathways.

Claimed effects: Improves charge delocalisation and can create regular transport paths through metal-ligand chains or pi-d conjugation.

Controlling variables: linker symmetry · chelating functional group · metal-node identity · metal-ligand orbital overlap

Representative materials: Mn2(DSBDC)(DMF)2 · Ni3(HITP)2 · Cu3(HHTP)2

Caveat: The review treats this at concept level; primary papers are needed to confirm exact conductivity and structural assignments.

p003 · Specific Linkers

Template-assisted nanosheet and heterostructure growth

Use templates or sacrificial MOF precursors to suppress crystal growth in one direction and generate ultrathin 2D MOF or MOF-derived heterostructures.

Claimed effects: Promotes 2D nanosheet morphology and can integrate higher-conductivity supports or derived phases.

Controlling variables: template chemistry · growth directionality · graphene sheet integration · post-synthetic sulfidation

Representative materials: nickel-squarate MOF nanosheets · 2D Ni-MOF/graphene nanosheet stacks · 2D nickel sulfide/GNS heterostructure

Caveat: The MOF can become a precursor or sacrificial template, so final electrode chemistry may no longer be a pristine MOF.

p003 · Loading with conducting polymers

Top-down delamination or mechanical exfoliation

Use delamination or ball milling to produce ultrathin nanosheets from layered conductive MOFs.

Claimed effects: Exposes more active sites, shortens ion-diffusion paths and improves processability for micro-supercapacitors.

Controlling variables: layer thickness · crystallinity · mechanical exfoliation conditions · solution processability

Representative materials: HHB-Cu nanosheets · HHTP-Cu nanosheets · Ni2(CuPc(NH)8) nanosheets

Caveat: Exfoliation benefits are coupled to carbon additives in some device demonstrations.

p002 · Origin of electrical conductivity in MOFs

Review claims

These are the review authors’ synthesis, not newly measured results.

Author InterpretationHigh supportDefinition Scope

The review treats 2D conducting MOFs as a distinct subset of 2D MOFs because their elevated conductivity and transport pathways differ from conventional low-conductivity MOFs.

Evidence basis: review_reasoning

Caveat: The boundary is conceptual and material-specific rather than a single conductivity threshold.

p001 · Introduction

Author InterpretationHigh supportCaveat

The review states that few studies provide in-depth investigation of charge-transport mechanisms in MOFs, limiting mechanistic certainty.

Evidence basis: review_reasoning

Caveat: This is the review authors' assessment of the literature up to 2020.

p002 · Origin of electrical conductivity in MOFs

Author InterpretationHigh supportCaveat

Guest-promoted transport can create conduction pathways, but bulky guest inclusion may block pores and reduce or eliminate porosity.

Evidence basis: review_reasoning

Caveat: Important for interpreting conductivity improvements in energy-storage electrodes where ion access remains essential.

p002 · Guest-Promoted Transport · Fig. 3

ContestedHigh supportControversy

The review cautions that band-like and hopping transport can be hard to distinguish in polycrystalline MOFs because defects and grain boundaries obscure intrinsic behaviour.

Evidence basis: review_reasoning

Caveat: Applies especially to polycrystalline samples and lower-temperature transport analysis.

p002 · Redox Hopping

SpeculativeMedium supportCaveat

The review suggests that most conductivity improvement has been in-plane and that tuning the interlayer gap could promote out-of-plane charge conduction.

Evidence basis: review_reasoning

Caveat: Presented as a perspective rather than a demonstrated design rule.

p008 · Conclusions and Perspectives

DescriptiveHigh supportDefinition Scope

A typical 2D conducting MOF consists of coordinated organic linkers and metal nodes forming layered lattices with open nanochannels between pi-stacked sheets.

Evidence basis: review_reasoning

Caveat: The description generalises common frameworks; individual stacking and pore symmetry vary with linker and metal selection.

p001 · Fundamentals and History of 2D conducting MOFs · Fig. 2

Consensus SummaryHigh supportStructure Property Link

Planar conjugated linkers with ortho-substituted donor groups and transition-metal nodes promote square-planar coordination, pi-d hybridisation and in-plane charge delocalisation.

Evidence basis: multi_reference

Caveat: The review does not deeply analyse band structures; it points readers to specialist conductivity reviews.

p001 · Fundamentals and History of 2D conducting MOFs

Consensus SummaryMedium supportApplication Relevance

For Li-S batteries, the review argues that 2D conducting MOFs can act as sulfur hosts with active binding sites and conductivity that help suppress polysulfide dissolution and improve utilisation.

Evidence basis: multi_reference

Caveat: The review mixes computational and composite-electrode evidence; primary-paper details are needed for quantitative conclusions.

p005 · Li-Sulphur batteries · Fig. 7; Fig. 8

Author InterpretationMedium supportApplication Relevance

The review highlights Ni-HITP as a LIB example where both anions and cations participate in charge storage, implying that anion conductivity as well as cation conductivity can matter.

Evidence basis: single_reference

Caveat: This is based on one highlighted demonstration and should not be generalised to all 2D conducting MOF cathodes.

p004 · Li-ion Batteries · Fig. 5

Author InterpretationHigh supportMeasurement Interpretation

The review argues that XPS, XRD, electron microscopy and gas adsorption are insufficient by themselves to resolve molecular ion-electrode interactions and pore-volume effects in working EES electrodes.

Evidence basis: multi_reference

Caveat: The review also states that NMR faces sensitivity and resolution challenges in conductive/composite materials.

p007 · Advanced characterization techniques and importance of NMR · Fig. 13

Consensus SummaryMedium supportTransport Mechanism

Extended pi-d conjugation in 2D planes is presented as an overriding mechanism for enhanced conductivity in many conducting MOFs.

Evidence basis: multi_reference

Caveat: The review also notes interlayer pi-pi interactions and redox effects, so this mechanism should not be assumed exclusive.

p002 · Protracted conjugation · Fig. 3

Consensus SummaryHigh supportStructure Property Link

Non-innocent organic linkers can add ligand redox capacity alongside metal-node redox activity, increasing charge-storage capability.

Evidence basis: multi_reference

Caveat: The review notes that only a few redox-active materials are currently known.

p004 · Li-ion Batteries · Fig. 6

Author InterpretationHigh supportCaveat

The review positions Na-ion batteries using 2D conducting MOFs as promising but still at an early stage compared with Li-ion work.

Evidence basis: review_reasoning

Caveat: The review also notes general SIB issues such as larger Na-ion size and dendrite/safety concerns.

p004 · 2D conducting MOFs in EES: Challenges and remedies

Author InterpretationHigh supportStructure Property Link

The review interprets later HAB and Cu-DBC supercapacitor results as showing that redox-active ligands and metal centres can move 2D MOF supercapacitors beyond simple EDL storage.

Evidence basis: multi_reference

Caveat: Early EDL capacitance in Ni3(HITP)2 was described as not very impressive and redox-active mechanisms were initially overlooked.

Research gaps

Open questions are presented as review-author priorities, not conclusions from the primary database.

Out-of-plane conduction

Medium

Conductivity has mainly improved in-plane; out-of-plane/interlayer conduction remains an opportunity.

Proposed direction: Tune interlayer gap and pi-electron overlap between consecutive layers.

p008 · Conclusions and Perspectives

Li-ion storage mechanisms

High

Effective ion transport is recognised as important for fast charging, but Li-ion storage mechanisms and coupled ionic/electronic transport in 2D conducting MOF cathodes remain insufficiently understood.

Proposed direction: Study Li-ion storage mechanisms together with ionic and electronic transport properties in next-generation MOF cathodes.

p005 · Li-ion Batteries

Charge-transport mechanism

High

Few studies provide in-depth mechanistic investigation of charge transport in MOFs, making it hard to state transport mechanisms definitively.

Proposed direction: Combine variable-temperature conductivity, electronic-structure calculations, optical spectroscopy and device measurements.

p002 · Origin of electrical conductivity in MOFs

Advanced characterisation

High

Very limited advanced studies, including NMR, have been used to study ion dynamics, pore volume and nanopore effects on charge storage.

Proposed direction: Use in-situ, operando and solid-state NMR alongside diffraction, spectroscopy and modelling.

p008 · Conclusions and Perspectives

Redox-active linker discovery

Medium

The review states that more redox-active organic linkers are needed and only a few redox-active materials are currently known.

Proposed direction: Design and screen additional redox-active planar organic linkers that preserve conductivity and porosity.

p008 · Conclusions and Perspectives

Scale-up and commercialisation

High

Limited MOF yield is presented as a serious concern for commercial application at large scale.

Proposed direction: Develop production technologies for scalable synthesis and electrode assembly.

p008 · Conclusions and Perspectives

Na-ion battery maturity

Medium

Na-ion battery research using 2D conducting MOF electrodes is described as still in its infancy.

Proposed direction: Develop robust 2D conducting MOF electrodes with pore sizes and redox sites suited to Na-ion transport and stability.

p004 · 2D conducting MOFs in EES: Challenges and remedies

Zn-ion battery exploration

Medium

Although 2D conducting MOF cathodes are promising for ZIBs, the review says they have rarely been explored.

Proposed direction: Explore compatible pore sizes, layer gaps and redox-active frameworks for aqueous Zn2+ insertion/extraction.
