Author interpretations and caveats

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

Application RelevanceSupport assessment: High

Cu3(HHTP)2/GCE is selective for dopamine over ascorbic acid under the tested conditions.

Caveat: Selectivity is demonstrated for AA and DA in the reported concentration comparison, not for a broad interferent panel.

p004 (journal p.525) · 3.2 Electrochemical sensing of DA · Figure 3 · Linked to 2 structured results

Application RelevanceSupport assessment: High

The Cu3(HHTP)2/GCE sensor provides a wide dopamine linear range, low detection limit, stability, reproducibility and acceptable serum recovery.

Caveat: Serum applicability is supported by three spiked serum rows in SI Table S1; broader biological matrices are not tested.

p006 (journal p.527) · 4 Conclusions · Linked to 8 structured results

Application RelevanceSupport assessment: High

Cu3(HHTP)2/GCE gives acceptable dopamine recovery in spiked human serum samples, with recoveries of 99.5-105% and RSD values below 5%.

Caveat: Only three serum spike levels are reported.

Phase AssignmentSupport assessment: High

PXRD confirmed successful synthesis of Cu3(HHTP)2 with in-plane and axial long-range order expected for covalently linked layered materials.

Caveat: No CIF or full structural refinement is provided in the assigned documents.

Structure Property LinkSupport assessment: Medium

The authors attribute the high conductivity and sensing response of Cu3(HHTP)2 to highly conjugated organic linkers and d9 Cu(II) centres, enabling long-range delocalised electrons and increased electron density.

Caveat: The paper does not report a first-hand electrical conductivity value for its Cu3(HHTP)2 sample.

Transport MechanismSupport assessment: High

The dopamine electrochemical reaction on Cu3(HHTP)2/GCE is diffusion-controlled because peak currents are proportional to the square root of scan speed.

Caveat: The extracted evidence is the authors' reported proportional trend; fitted slopes are not tabulated.
