Review claims

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

Author InterpretationHigh supportApplication Relevance

ECMOFs are argued to be attractive battery electrodes because robust frameworks, designable channels, redox sites and conductivity can aid ion diffusion, capacity and rate performance.

Evidence basis: multi_reference

Caveat: The review calls for deeper storage-mechanism evidence, especially for Li-ion and Na-ion cases.

3 · ECMOFs for Li-ions batteries

Author InterpretationHigh supportStructure Property Link

Electrical conductivity is treated as a critical factor for rate performance because it facilitates electron transfer from active substances to substrates during electrochemical reactions.

Evidence basis: review_reasoning

Caveat: Device performance also depends on ion transport, morphology and mass loading.

2 · Hopping transport

Consensus SummaryHigh supportDefinition Scope

Conventional MOFs are usually electrical insulators, and this limitation motivates the direct development of intrinsically conductive redox-active MOFs for electrochemical electrodes.

Evidence basis: multi_reference

Caveat: The review gives a general threshold rather than a standardised measurement protocol.

1 · Introduction

Author InterpretationMedium supportSynthesis Strategy

Direct growth of ECMOFs on substrates is interpreted as a way to decrease interface resistance and improve binder-free electrode performance.

Evidence basis: single_reference

Caveat: The review does not separate interface effects from mass loading, morphology or electrolyte effects.

2 · ECMOFs for supercapacitors · Fig. 6

DescriptiveHigh supportDefinition Scope

ECMOFs are framed as hybrid materials formed by coordination of metallic nodes to organic ligands that combine conductivity and redox activity.

Evidence basis: review_reasoning

Caveat: The definition is review-level terminology, not a universally enforced nomenclature.

1 · Conductive mechanisms of ECMOFs

Author InterpretationHigh supportCaveat

Although ECMOF electrocatalysis is a growing hotspot, the review cautions that performance was not yet comparable with noble-metal catalysts and needs mechanistic and stability studies.

Evidence basis: review_reasoning

Caveat: This is a 2020/2021 review-level judgement and should not be treated as current beyond the review period.

6 · Conclusions and future perspectives

Consensus SummaryHigh supportTransport Mechanism

Hopping transport is described as thermally dependent charge transfer between discrete redox sites with probability controlled by site distance and energy difference.

Evidence basis: review_reasoning

Caveat: The review gives a model equation but does not assess all experimental fits.

2 · Hopping transport

Author InterpretationHigh supportDefinition Scope

For electrochemical design, the review distinguishes intrinsic framework conductivity from conductivity caused by guest doping or ionic motion through pores.

Evidence basis: review_reasoning

Caveat: Guest-enhanced conductivity is acknowledged but excluded from the review's ECMOF scope.

1 · Conductive mechanisms of ECMOFs

Author InterpretationHigh supportSynthesis Strategy

Selecting planar pi-conjugated linkers and redox-active metal centres is presented as a primary strategy for raising ECMOF conductivity.

Evidence basis: multi_reference

Caveat: The review does not isolate linker effects from morphology or processing.

2 · Manipulating π-electron interactions · Fig. 3

DescriptiveMedium supportApplication Relevance

For sensing, ECMOF responses can be modulated by adsorbate identity and by ligand/metal-node selection in phthalocyanine molecular meshes.

Evidence basis: single_reference

Caveat: The review provides selected examples, not a broad sensor-performance meta-analysis.

2 · ECMOFs in electrochemical-sensing devices · Fig. 5

Author InterpretationMedium supportStructure Property Link

In Li-S and Na-I2 batteries, ECMOF pores and metal nodes are presented as ways to trap polysulfides or polyiodides while maintaining conductivity.

Evidence basis: multi_reference

Caveat: The review says the role of metallic moieties and trapping mechanisms still needs more research.

4 · ECMOFs for Li-S batteries · Fig. 11

Author InterpretationHigh supportStructure Property Link

For supercapacitors, ECMOFs are positioned as promising because they can combine electrical conductivity, controlled porosity, surface area and redox sites.

Evidence basis: multi_reference

Caveat: The review explicitly notes supercapacitor applications remain early-stage.

2 · ECMOFs for supercapacitors

Consensus SummaryHigh supportTransport Mechanism

The review adopts a three-part mechanism taxonomy for intrinsic ECMOF conductivity: through-space, through-bond and hopping transport.

Evidence basis: review_reasoning

Caveat: Individual materials may involve coupled pathways; the taxonomy is simplifying.

1 · Conductive mechanisms of ECMOFs · Fig. 2

Consensus SummaryHigh supportTransport Mechanism

Through-bond conduction is linked to suitable spatial and energetic overlap of metal-node and ligand frontier orbitals, especially with N- or S-coordinating linkers.

Evidence basis: multi_reference

Caveat: Quantitative comparison depends on contact geometry, morphology and measurement method in the primary studies.

1 · Through-bond mechanism

Consensus SummaryMedium supportTransport Mechanism

Through-space conduction is attributed to non-covalent interactions such as pi-pi stacking, with closer spatial separation improving transfer and mobility.

Evidence basis: multi_reference

Caveat: The review draws an analogy to organic semiconductors and cites examples rather than proving the mechanism for all ECMOFs.
