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.
Cu-TOC delivers the highest initial reversible capacity among the three M-TOCs at 50 mA g-1, attributed to superior conductivity and joint metal-node/ligand redox participation.
Caveat: Electrochemical data are from composite electrodes containing carbon black and PVDF, not neat MOF films.
p.9 · 3. Conclusion · Linked to 4 structured results
Using a Nafion membrane improves Cu-TOC long-term cycling relative to glass fibre, attributed to cation selectivity preventing anion crossover.
Caveat: Nafion result is reported qualitatively as maintaining all capacity; exact plotted value was not available from SI text.

The M-TOC frameworks are chemically robust to 3-day soaking in DMF, DCM, THF, methanol, acetonitrile and water by PXRD comparison.
Caveat: Qualitative PXRD stability assessment; rendered SI verifies the figure but no numeric stability metric is reported.

Cu-TOC is assigned to an AB-stacked tetragonal Pmma structure, whereas Zn-TOC and Mn-TOC are assigned to AA-stacked P4/mmm structures.
Caveat: Assignments are based on PXRD profile fitting combined with simulated structures rather than single-crystal structures of the MOFs.

UPS indicates the Fermi level approaches the HOMO edge in the order Mn-TOC, Zn-TOC, Cu-TOC, which the authors link to enhanced conductivity.
Caveat: The link is interpretive and based on UPS trends plus conductivity data.
p.5 · 2.2 · Figure 3g · Linked to 6 structured results
Capacitive processes dominate the electrochemical kinetics of the M-TOCs across the measured scan rates, supporting their rate capability.
Caveat: Several scan-rate contribution values are read from figure labels rather than text tables.
p.7 · 2.6 · Figure 6j-l · Linked to 10 structured results
All three M-TOCs show semiconducting temperature-dependent conductivity following Arrhenius behaviour, with Cu-TOC having the highest room-temperature conductivity and lowest activation energy.
Caveat: Transport measured on pressed-powder pellets; grain-boundary effects may contribute.
