Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Cu3(HHTP)2 is reported to be stable in air over 30 days, with little change in morphology, XRD patterns or FT-IR spectra.
Caveat: The stability evidence is qualitative from figures and text; no quantified retained signal is reported.
main p.8, article p.22923 · Determination of MG · Figures S20-S22 · Linked to 3 structured results
Cu-MOF/CPE measurements in fish, water and shrimp samples agreed closely with ELISA/reference values, supporting practical MG analysis.
Caveat: The 30-day fish row in Table 1 has no numeric sensor or ELISA value in the text/rendered table.
main p.9, article p.22924 · Analysis of MG in Actual Samples · Table 1; Table S2 · Linked to 7 structured results
The Cu-MOF/CPE ratiometric DPV sensor detects MG over 5-1000 nM with a 1.34 nM detection limit and acceptable repeatability/reproducibility.
Caveat: The SI LOD section contains a likely unit typo stating 5-1000 uM, inconsistent with the main text and calibration figure.
main p.8, article p.22923 · Determination of MG · Figure 6; Figure S19 · Linked to 4 structured results
In Cu-MOF/CPE, Cu3(HHTP)2 supplies both catalytic MG oxidation activity and a copper oxidation internal-reference peak for ratiometric sensing.
Caveat: Ratiometric performance is demonstrated in a carbon paste composite, so it should not be interpreted as a standalone powder sensor.
main p.7, article p.22922 · Electrochemical Characteristics of MG · Figure 5 · Linked to 5 structured results
The M3(HHTP)2 nanorods are p-d conjugated two-dimensional sheets stacked in an AA manner, forming an extended three-dimensional pore network.
Caveat: No CIF was assigned in the prompt; structural assignment is based on reported XRD/FT-IR and simulated structure figures.
main p.4, article p.22919 · Characterization and Properties · Figure 2 · Linked to 7 structured results
Cu3(HHTP)2/CPE outperforms the Ni and Co analogues because it combines the highest BET surface area, largest pore size, largest Cdl, largest effective electrode area and lowest RCT.
Caveat: Charge-transfer resistance is measured on the MOF/CPE composite electrode, not on a standalone pristine powder pellet or film.
main p.5, article p.22920 · Characterization and Properties · Figures 2, S3-S8 · Linked to 5 structured results
DMF acts as a limiting reagent/modulator that regulates coordination equilibrium, framework extension and crystal aggregation, producing larger-aspect-ratio M3(HHTP)2 nanorods.
Caveat: Mechanistic explanation is qualitative and no numerical aspect ratios were reported.
main p.4, article p.22919 · Characterization and Properties · Figure S1 · Linked to 1 structured result
MG oxidation on Cu-MOF/CPE is an adsorption-controlled, irreversible two-electron/two-proton electrochemical process.
Caveat: Electron count relies on the common assumption alpha = 0.5 in the Laviron analysis.
