Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.
A small residual bismuth acetate impurity is present in Bi(HHTP) 12 h, but the authors argue it has negligible influence on electrochemical performance.
Caveat: The impurity estimate is based on XRD response-factor assumptions and SI control mixtures, not direct quantitative chemical analysis.

After 3 M KOH soaking, weakened Bi-plane XRD peaks are attributed to adsorbed potassium-containing species, while retained benzene-backbone and FT-IR catecholate features are used to argue Bi(HHTP) integrity.
Caveat: Post-soaking XRD changes are substantial, and the integrity conclusion is qualitative.

Hydrothermal reaction duration controls nanobelt length, and the 12 h Bi(HHTP) nanobelts combine the best conductivity, longest nanobelts, highest capacitance, and best cycling retention.
Caveat: No uncertainty or replicate statistics are reported for the conductivity or electrochemical values.
p007 / article p.4832 · Conclusions · Linked to 4 structured results
Bi ions in BiO4 linkages act as redox-active faradaic sites, contributing to battery-type charge storage and higher capacitance.
Caveat: Based on XPS peak assignments and electrochemical signatures rather than operando speciation.

The authors attribute Bi(HHTP) conductivity to pi-pi coupling between layers and pi-d orbital overlap between O and Bi atoms.
Caveat: Mechanistic assignment is inferential; no direct electronic-structure measurement is reported in this paper.
p005 / article p.4830 · Structural and physicochemical characterization · Figure 4 · Linked to 4 structured results
Charge storage in Bi(HHTP) electrodes involves both semi-infinite diffusion-controlled battery-type behaviour and surface-controlled capacitive behaviour.
Caveat: Capacitive contribution percentages beyond the 100 mV s^-1 figure-read value were not fully digitised.
