Coordinatively unsaturated metal-bis(dithiolene) planes are presented as gas-sensing/adsorption sites whose electronic response can be modulated by CO, NO or O2 adsorption.
Evidence basis: multi_reference
Caveat: Much of this section is based on first-principles calculation rather than device measurements.
29 · 4.3. Adsorption and separation
Author InterpretationHigh supportMeasurement Interpretation
For metastable metal-dithiolene frameworks, intrinsic transport measurements should be performed in vacuum or inert atmosphere because air exposure can oxidise metal centres and ligands.
Evidence basis: multi_reference
Caveat: The review gives examples but not a universal protocol for every framework.
4 · 1. Introduction (Challenges and Opportunities)
Author InterpretationHigh supportTransport Mechanism
The review interprets conductivity in 2D metal-dithiolene frameworks as sensitive to oxidation state and doping, with reduction or oxidation changing conductivity by orders of magnitude.
Evidence basis: multi_reference
Caveat: Different materials and dopants should not be directly compared without primary-method details.

Author InterpretationHigh supportStructure Property Link
Dithiolene linkers confer rigidity, pi-conjugation and redox activity, which can modulate electronic properties in metal-dithiolene MOFs.
Evidence basis: multi_reference
Caveat: Structural disorder and film morphology can dominate macroscopic transport.

Author InterpretationHigh supportCaveat
Applications of metal-sulfur MOFs are still at an initial stage, with several areas relying heavily on theoretical studies.
Evidence basis: review_reasoning
Caveat: The field has likely advanced after the review's 2021 literature window, but no network update was permitted.
32 · 5. Concluding remarks and perspectives
Consensus SummaryHigh supportSynthesis Strategy
Interfacial synthesis confines growth in two dimensions and is presented as a key route to crystalline large-area 2D metal-sulfur films or monolayers.
Evidence basis: multi_reference
Caveat: Surface energy, interface composition and concentration strongly affect film quality.
16 · 3.1. Interfacial synthesis
Consensus SummaryHigh supportHistorical Development
MOFs historically lagged in electrochemical and electronic-device uses because many frameworks lacked adequate electrical conductivity.
Evidence basis: multi_reference
Caveat: The review states this broadly; primary support should come from cited conductive-MOF literature.

Author InterpretationHigh supportSynthesis Strategy
Masked thiol ligands can reduce thiol reactivity and enable higher-crystallinity MOFs, including single-crystal HTT-Pb.
Evidence basis: single_reference
Caveat: The review presents HTT-Pb as a notable success rather than a universal outcome.

Consensus SummaryMedium supportMaterial Comparison
For M-BHT and M-BT electrocatalysis, the review emphasises metal identity as a determinant of HER activity and active-site electronic structure.
Evidence basis: multi_reference
Caveat: The review mixes experimental and theoretical evidence; primary comparisons should be normalised before quantitative use.
28 · 4.2.1. Hydrogen evolution reaction (HER)
Author InterpretationMedium supportMaterial Comparison
The review treats organic metal chalcogenides as an adjacent 2D conductive material class that broadens design space for tunable band gaps and conductivity.
Evidence basis: multi_reference
Caveat: OMCs are adjacent to, rather than identical with, conventional porous MOFs.
26 · 4.1. Conductivity
Author InterpretationMedium supportApplication Relevance
High conductivity alone is insufficient for HER: porosity and exposed active sites affect substrate/product transfer, explaining why Cu-BHT nanoparticles can outperform dense films catalytically.
Evidence basis: single_reference
Caveat: Catalytic rankings depend on morphology and electrochemical test conditions.

Consensus SummaryHigh supportSynthesis Strategy
Post-synthetic modification of thiol-functional MOFs can convert accessible thiols into catalytic, adsorption or proton-conducting functions while retaining robust frameworks.
Evidence basis: multi_reference
Caveat: Requires stable parent frameworks, usually UiO/Zr-type, and careful control of thiol reactivity.
24 · 3.2.3. Post-synthetic method
Author InterpretationHigh supportCaveat
For many dithiolate MOFs, structure-performance relationships are hindered because single-crystal structures are difficult and structure determination often relies on simulation.
Evidence basis: review_reasoning
Caveat: The caveat does not apply equally to carboxyl-thiol frameworks with single-crystal structures.

Author InterpretationHigh supportTransport Mechanism
Thiol and metal-sulfur motifs are interpreted as promoting orbital overlap and charge delocalisation through covalent, polarizable metal-sulfur links.

THT-Co and THT-Fe are presented as examples where temperature-dependent semiconductor-to-metal transitions relate to doping, film thickness and charge delocalisation.

Caveat: The review reports interpretation at a high level; detailed transport mechanism requires the primary studies.
25 · 4.1. Conductivity
Author InterpretationHigh supportStructure Property Link
Carboxyl-thiol bifunctional linkers balance crystallinity, stability and sulfur functionality because carboxylates build robust hard-metal frameworks while thiols remain accessible or coordinate selectively.
Evidence basis: multi_reference
Caveat: Electronic transport is not necessarily high unless sulfur participates in charge-transfer pathways.

The review's core organising split is between soft-metal dithiolene frameworks and hard-metal carboxyl-thiol frameworks.
