Open a family to keep every result attached to its sample, method and conditions.
Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
ITO/NMOF-1/Al devices act as Schottky barrier diodes with high rectification ratios at +/-1 V, improved under photoirradiation.

NMOF-1 is a pristine semiconducting and photoconducting MOF film whose conductivity increases under illumination.

The reported CV reduction value is internally inconsistent between main-text peak reporting and the SI band-gap calculation.
Caveat: Use electrochemical band gap values as reported, but note the reduction-potential discrepancy.

Gas/vapour adsorption supports microporous, hydrophobic pores in NMOF-1.
Caveat: N2 isotherm is type II surface adsorption; microporosity assignment relies mainly on CO2 uptake and structural model.

Zn coordination in NMOF-1 provides a more effective periodic pathway for electron flow than the H2OPE-C12 ligand control.

Dodecyl-chain surface projection and hierarchical roughness give NMOF-1-coated glass superhydrophobic and self-cleaning behaviour.
Caveat: Associated self-cleaning video was not supplied locally, but quantitative contact/sliding angles are reported in text.

Illumination improves SBD charge transport, increasing mobility and diffusion length while lowering series resistance and barrier height.
4-5 · Results and Discussion · Tables S2-S3 · Linked to 8 structured results
The authors assign dominant charge transport to through-bond transfer along the 1D Zn-OPE coordination chain rather than through-space pi stacks.
Caveat: Mechanism is based on modelled fragments and DOS/orbital calculations rather than direct directional transport measurements.
