Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

CaveatSupport assessment: High

The 1D-CuTABQ conductivity is reported as 9.7 x 10^-3 S m^-1 in the main text but 9.3 x 10^-3 S/m in the SI Figure S11 caption.

Caveat: Both values are retained rather than corrected.

Structure Property LinkSupport assessment: High

The porous 2D framework improves dual-ion storage, rate capability and long-cycle stability relative to 1D-CuTABQ despite lower bulk pellet conductivity.

Caveat: Electrochemical electrodes are composites with carbon and PVDF, so device performance is not a pristine-powder transport measurement.

Synthesis MechanismSupport assessment: High

Changing reaction atmosphere, base availability, temperature and confinement directs the same Cu/TABQ chemistry to 1D square-planar CuTABQ or 2D octahedral mixed-valence CuTABQ.

Caveat: Valence assignments are inferred from spectroscopy and elemental ratios, not single-crystal structures.

Transport MechanismSupport assessment: High

Charge storage involves ligand C=O/C-O redox with Na+ insertion/extraction, Cu2+/Cu+ redox, and PF6- anion storage at high voltage; the anion process is stronger in 2D-CuTABQ.

Caveat: Some mechanistic assignments are ex situ and may not capture transient states.
