Planar 2D pi-conjugated MOFs are described as the most conductive MOFs known at the time of the review.

Deriving fundamental band gaps from activation energies or optical absorption can be misleading for doped MOFs and excitonic materials.
Evidence basis: review_reasoning
Caveat: UPS/IPES are presented as more direct but less common approaches.

Author InterpretationMedium supportTransport Mechanism
Band transport is presented as the ultimate target for highest conductivity because charge delocalisation tends to give higher mobility than hopping.
Evidence basis: review_reasoning
Caveat: The review later warns that few conductive MOFs have definitive mechanism evidence.

Computational screening is expected to become important for identifying host-guest pairs that become conductive upon guest insertion.

Conductive MOF design must address both carrier density and mobility; high values of only one parameter are insufficient.

Caveat: Equation-based physical framing rather than a material-specific measurement.

Cu[Cu(pdt)2] is interpreted as likely conducting through Cu(pyrazine) sheets and dithiolene units, with CuII unpaired electrons increasing charge density.
Evidence basis: single_reference
Caveat: The review explicitly notes charge hopping via dithiolene units cannot be ruled out.

Replacing MnII with FeII in DOBDC/DSBDC analogues introduces minority-spin carriers and greatly increases conductivity, making metal identity a key design variable.
Evidence basis: multi_reference
Caveat: Review notes these systems are still better described by hopping because calculated bands are narrow.

High bulk conductivity in HITP-based 2D MOFs enabled early MOF chemiresistive sensors, with metal-node choice affecting ammonia response.

Iodine exposure of Cu[Ni(pdt)2] is interpreted as partial oxidation of the framework, not conduction through iodine guests, increasing conductivity by four orders of magnitude.
Evidence basis: single_reference
Caveat: The argument relies on the review's interpretation of small iodine loading and redox activity.

Conductivity comparisons require method, morphology, atmosphere, temperature and light exposure context; ideal intrinsic comparisons use four-probe single-crystal or van der Pauw single-domain-film measurements.
Evidence basis: review_reasoning
Caveat: Ideal conditions may be experimentally infeasible for some MOFs.

The intended design pathway in a MOF need not match the operative transport mechanism, and assigning hopping or band models is premature for most examples.

TRMC and FET mobility measurements should not be used interchangeably because they probe different length scales, fields and current regimes.

Caveat: Both methods remain useful for different questions.

Most conventional MOFs are poor electrical conductors because hard metal ions and redox-inactive ligands do not provide low-energy pathways or free carriers.

Pressed pellets are accessible but can mask anisotropy and underestimate intrinsic conductivity because of grain boundaries and random crystallite orientation.

For 2D MOFs, intra-sheet transport may dominate, but stacking geometry controls inter-sheet transport and remains largely uncontrolled.

In M2(TTFTB), conductivity correlates with metal cation radius through shorter S...S contacts and improved TTF orbital overlap rather than metal-carboxylate chain transport.
