Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
Bi-HHTP/COF/GCE enables simultaneous Cd2+ and Pb2+ quantification with low ug/L detection limits and acceptable recovery in water and food samples.
Caveat: Raw DPASV curves for real samples are in SI Fig. S6; Table 2 values are available in the main article, while the SI text has captions and the rendered SI surrogate was checked.

The supplementary-information text contains captions for supporting Figs. S1-S6 and the rendered SI surrogate shows the panels; exact numeric extraction still relies on text/table values where available because several SI axes are only visually readable.
Caveat: No network retrieval was attempted; no missing SI request remains open because the local rendered SI surrogate satisfies visual-check needs.

Bi-HHTP/COF composite formation is supported by SEM/TEM morphology and XPS detection of O, N, Bi and C with shifted binding energies after combining Bi-HHTP and COF.
Caveat: Composite XRD details are not described in the main text; supplied SI text confirms Fig. S1 captions and the rendered SI surrogate shows the plotted panels.

The Bi-HHTP/COF electrode gives the best charge-transfer and sensing response because conductive Bi-HHTP, porous COF and their cooperative interaction increase surface area, electron transfer and Cd2+/Pb2+ adsorption/alloying capability.
Caveat: Direct bulk electrical conductivity was not reported; the electronic-conductivity claim is inferred by the authors from electrochemical response and EIS.
